GENERAL DESCRIPTION
The ADSP-BF561 processor is a high performance member of
the Blackfin family of products targeting a variety of multimedia, industrial, and telecommunications applications. At the
heart of this device are two independent Analog Devices
Blackfin processors. These Blackfin processors combine a dualMAC state-of-the-art signal processing engine, the advantage of
a clean, orthogonal RISC-like microprocessor instruction set,
and single instruction, multiple data (SIMD) multimedia capabilities in a single instruction set architecture.
The ADSP-BF561 processor has 328K bytes of on-chip memory.
Each Blackfin core includes:
The powerful 40-bit shifter has extensive capabilities for performing shifting, rotating, normalization, extraction, and
depositing of data. The data for the computational units is
found in a multiported register file of sixteen 16-bit entries or
eight 32-bit entries.
A powerful program sequencer controls the flow of instruction
execution, including instruction alignment and decoding. The
sequencer supports conditional jumps and subroutine calls, as
well as zero overhead looping. A loop buffer stores instructions
locally, eliminating instruction memory accesses for tight
looped code.
Two data address generators (DAGs) provide addresses for
simultaneous dual operand fetches from memory. The DAGs
share a register file containing four sets of 32-bit Index, Modify,
Length, and Base registers. Eight additional 32-bit registers
provide pointers for general indexing of variables and stack
locations.
• 16K bytes of instruction SRAM/cache
• 16K bytes of instruction SRAM
• 32K bytes of data SRAM/cache
• 32K bytes of data SRAM
• 4K bytes of scratchpad SRAM
Additional on-chip memory peripherals include:
• 128K bytes of low latency on-chip L2 SRAM
• Four-channel internal memory DMA controller
• External memory controller with glueless support for
SDRAM, mobile SDRAM, SRAM, and flash.
PORTABLE LOW POWER ARCHITECTURE
Blackfin processors provide world-class power management
and performance. Blackfin processors are designed in a low
power and low voltage design methodology and feature
dynamic power management, the ability to vary both the voltage
and frequency of operation to significantly lower overall power
consumption. Varying the voltage and frequency can result in a
substantial reduction in power consumption, compared with
just varying the frequency of operation. This translates into
longer battery life for portable appliances.
BLACKFIN PROCESSOR CORE
As shown in Figure 2, each Blackfin core contains two multiplier/accumulators (MACs), two 40-bit ALUs, four video ALUs,
and a single shifter. The computational units process 8-bit,
16-bit, or 32-bit data from the register file.
Each MAC performs a 16-bit by 16-bit multiply in every cycle,
with accumulation to a 40-bit result, providing eight bits of
extended precision. The ALUs perform a standard set of arithmetic and logical operations. With two ALUs capable of
operating on 16-bit or 32-bit data, the flexibility of the computation units covers the signal processing requirements of a varied
set of application needs.
Each of the two 32-bit input registers can be regarded as two
16-bit halves, so each ALU can accomplish very flexible single
16-bit arithmetic operations. By viewing the registers as pairs of
16-bit operands, dual 16-bit or single 32-bit operations can be
accomplished in a single cycle. By further taking advantage of
the second ALU, quad 16-bit operations can be accomplished
simply, accelerating the per cycle throughput.
Rev. A |
Blackfin processors support a modified Harvard architecture in
combination with a hierarchical memory structure. Level 1 (L1)
memories are those that typically operate at the full processor
speed with little or no latency. Level 2 (L2) memories are other
memories, on-chip or off-chip, that may take multiple processor
cycles to access. At the L1 level, the instruction memory holds
instructions only. The two data memories hold data, and a dedicated scratchpad data memory stores stack and local variable
information. At the L2 level, there is a single unified memory
space, holding both instructions and data.
In addition, half of L1 instruction memory and half of L1 data
memory may be configured as either Static RAMs (SRAMs) or
caches. The Memory Management Unit (MMU) provides memory protection for individual tasks that may be operating on the
core and may protect system registers from unintended access.
The architecture provides three modes of operation: user mode,
supervisor mode, and emulation mode. User mode has
restricted access to certain system resources, thus providing a
protected software environment, while supervisor mode has
unrestricted access to the system and core resources.
The Blackfin instruction set has been optimized so that 16-bit
op-codes represent the most frequently used instructions,
resulting in excellent compiled code density. Complex DSP
instructions are encoded into 32-bit op-codes, representing fully
featured multifunction instructions. Blackfin processors support a limited multi-issue capability, where a 32-bit instruction
can be issued in parallel with two 16-bit instructions, allowing
the programmer to use many of the core resources in a single
instruction cycle.
The Blackfin assembly language uses an algebraic syntax for
ease of coding and readability. The architecture has been optimized for use in conjunction with the VisualDSP C/C++
compiler, resulting in fast and efficient software
implementations.

MEMORY ARCHITECTURE
Internal (On-Chip) Memory
The ADSP-BF561 views memory as a single unified 4G byte
address space, using 32-bit addresses. All resources including
internal memory, external memory, and I/O control registers
occupy separate sections of this common address space. The
memory portions of this address space are arranged in a hierarchical structure to provide a good cost/performance balance of
some very fast, low latency memory as cache or SRAM very
close to the processor, and larger, lower cost and performance
memory systems farther away from the processor. The
ADSP-BF561 memory map is shown in Figure 3.
The ADSP-BF561 has four blocks of on-chip memory providing
high bandwidth access to the core.
The L1 memory system in each core is the highest performance
memory available to each Blackfin core. The L2 memory provides additional capacity with lower performance. Lastly, the
off-chip memory system, accessed through the External Bus
Interface Unit (EBIU), provides expansion with SDRAM, flash
memory, and SRAM, optionally accessing more than
768M bytes of physical memory. The memory DMA controllers
provide high bandwidth data movement capability. They can
perform block transfers of code or data between the internal
L1/L2 memories and the external memory spaces.
Rev. A |
The first is the L1 instruction memory of each Blackfin core
consisting of 16K bytes of four-way set-associative cache memory and 16K bytes of SRAM. The cache memory may also be
configured as an SRAM. This memory is accessed at full processor speed. When configured as SRAM, each of the two 16K
banks of memory is broken into 4K sub-banks which can be
independently accessed by the processor and DMA.
The second on-chip memory block is the L1 data memory of
each Blackfin core which consists of four banks of 16K bytes
each. Two of the L1 data memory banks can be configured as
one way of a two-way set-associative cache or as an SRAM. The
other two banks are configured as SRAM. All banks are accessed
at full processor speed. When configured as SRAM, each of the
four 16K banks of memory is broken into 4K sub-banks which
can be independently accessed by the processor and DMA.
The third memory block associated with each core is a 4K byte
scratchpad SRAM which runs at the same speed as the L1 memories, but is only accessible as data SRAM (it cannot be
configured as cache memory and is not accessible via DMA).

Figure 3. Memory Map
The fourth on-chip memory system is the L2 SRAM memory
array which provides 128K bytes of high speed SRAM operating
at one half the frequency of the core, and slightly longer latency
than the L1 memory banks. The L2 memory is a unified instruction and data memory and can hold any mixture of code and
data required by the system design. The Blackfin cores share a
dedicated low latency 64-bit wide data path port into the L2
SRAM memory.
Each Blackfin core processor has its own set of core Memory
Mapped Registers (MMRs) but share the same system MMR
registers and 128K bytes L2 SRAM memory.
External (Off-Chip) Memory
The ADSP-BF561 external memory is accessed via the External
Bus Interface Unit (EBIU). This interface provides a glueless
connection to up to four banks of synchronous DRAM
Rev. A |
(SDRAM) as well as up to four banks of asynchronous memory
devices, including flash, EPROM, ROM, SRAM, and memory
mapped I/O devices.
The PC133-compliant SDRAM controller can be programmed
to interface to up to four banks of SDRAM, with each bank containing between 16M bytes and 128M bytes providing access to
up to 512M bytes of SDRAM. Each bank is independently programmable and is contiguous with adjacent banks regardless of
the sizes of the different banks or their placement. This allows
flexible configuration and upgradability of system memory
while allowing the core to view all SDRAM as a single, contiguous, physical address space.
The asynchronous memory controller can also be programmed
to control up to four banks of devices with very flexible timing
parameters for a wide variety of devices. Each bank occupies a
Page 6 of 60 |
May 2006
ADSP-BF561
64M byte segment regardless of the size of the devices used so
that these banks will only be contiguous if fully populated with
64M bytes of memory.
I/O Memory Space
Blackfin processors do not define a separate I/O space. All
resources are mapped through the flat 32-bit address space. Onchip I/O devices have their control registers mapped into memory mapped registers (MMRs) at addresses near the top of the
4G byte address space. These are separated into two smaller
blocks, one which contains the control MMRs for all core functions, and the other which contains the registers needed for
setup and control of the on-chip peripherals outside of the core.
The core MMRs are accessible only by the core and only in
supervisor mode and appear as reserved space by on-chip
peripherals. The system MMRs are accessible by the core in
supervisor mode and can be mapped as either visible or reserved
to other devices, depending on the system protection
model desired.
Booting
The ADSP-BF561 contains a small boot kernel, which configures the appropriate peripheral for booting. If the ADSP-BF561
is configured to boot from boot ROM memory space, the processor starts executing from the on-chip boot ROM.
Event Handling
The event controller on the ADSP-BF561 handles all asynchronous and synchronous events to the processor. The
ADSP-BF561 provides event handling that supports both nesting and prioritization. Nesting allows multiple event service
routines to be active simultaneously. Prioritization ensures that
servicing of a higher priority event takes precedence over servicing of a lower priority event. The controller provides support for
five different types of events:
• Emulation – An emulation event causes the processor to
enter emulation mode, allowing command and control of
the processor via the JTAG interface.
• Reset – This event resets the processor.
• Nonmaskable Interrupt (NMI) – The NMI event can be
generated by the software watchdog timer or by the NMI
input signal to the processor. The NMI event is frequently
used as a power-down indicator to initiate an orderly shutdown of the system.
• Exceptions – Events that occur synchronously to program
flow, i.e., the exception will be taken before the instruction
is allowed to complete. Conditions such as data alignment
violations or undefined instructions cause exceptions.
The ADSP-BF561 event controller consists of two stages: the
Core Event Controller (CEC) and the System Interrupt Controller (SIC). The Core Event Controller works with the System
Interrupt Controller to prioritize and control all system events.
Conceptually, interrupts from the peripherals enter into the
SIC, and are then routed directly into the general-purpose
interrupts of the CEC.
Core Event Controller (CEC)
The CEC supports nine general-purpose interrupts (IVG15–7),
in addition to the dedicated interrupt and exception events. Of
these general-purpose interrupts, the two lowest priority interrupts (IVG15–14) are recommended to be reserved for software
interrupt handlers, leaving seven prioritized interrupt inputs to
support the peripherals of the ADSP-BF561. Table 1 describes
the inputs to the CEC, identifies their names in the Event Vector
Table (EVT), and lists their priorities.

System Interrupt Controller (SIC)
The System Interrupt Controller provides the mapping and
routing of events from the many peripheral interrupt sources to
the prioritized general-purpose interrupt inputs of the CEC.
Although the ADSP-BF561 provides a default mapping, the user
can alter the mappings and priorities of interrupt events by writ-
• Interrupts – Events that occur asynchronously to program
flow. They are caused by timers, peripherals, input pins,
and an explicit software instruction.
Each event has an associated register to hold the return address
and an associated “return from event” instruction. When an
event is triggered, the state of the processor is saved on the
supervisor stack.

Event Control
The ADSP-BF561 provides the user with a very flexible mechanism to control the processing of events. In the CEC, three
registers are used to coordinate and control events. Each of the
registers is 16 bits wide, while each bit represents a particular
event class.
Page 8 of 60 |
• CEC Interrupt Latch Register (ILAT) – The ILAT register
indicates when events have been latched. The appropriate
bit is set when the processor has latched the event and
cleared when the event has been accepted into the system.
This register is updated automatically by the controller, but
may be written only when its corresponding IMASK bit is
cleared.
• CEC Interrupt Mask Register (IMASK) – The IMASK register controls the masking and unmasking of individual
events. When a bit is set in the IMASK register, that event is
unmasked and will be processed by the CEC when asserted.
A cleared bit in the IMASK register masks the event
thereby preventing the processor from servicing the event
even though the event may be latched in the ILAT register.
This register may be read from or written to while in super-

ler. DMA-capable peripherals include the SPORTs, SPI port,
UART, and PPI. Each individual DMA-capable peripheral has
at least one dedicated DMA channel.
visor mode. (Note that general-purpose interrupts can be
globally enabled and disabled with the STI and CLI
instructions.)
• CEC Interrupt Pending Register (IPEND) – The IPEND
register keeps track of all nested events. A set bit in the
IPEND register indicates the event is currently active or
nested at some level. This register is updated automatically
by the controller but may be read while in supervisor mode.
The SIC allows further control of event processing by providing
six 32-bit interrupt control and status registers. Each register
contains a bit corresponding to each of the peripheral interrupt
events shown in Table 2.
• SIC Interrupt Mask Register (SIC_IMASK0,
SIC_IMASK1) – This register controls the masking and
unmasking of each peripheral interrupt event. When a bit
is set in the register, that peripheral event is unmasked and
will be processed by the system when asserted. A cleared bit
in the register masks the peripheral event thereby preventing the processor from servicing the event.
• SIC Interrupt Status Register (SIC_ISR0, SIC_ISR1)–
As multiple peripherals can be mapped to a single event,
this register allows the software to determine which peripheral event source triggered the interrupt. A set bit indicates
the peripheral is asserting the interrupt; a cleared bit indicates the peripheral is not asserting the event.
• SIC Interrupt Wakeup Enable Register (SIC_IWR0,
SIC_IWR1) – By enabling the corresponding bit in this
register, each peripheral can be configured to wake up the
processor, should the processor be in a powered-down
mode when the event is generated.
Because multiple interrupt sources can map to a single generalpurpose interrupt, multiple pulse assertions can occur simultaneously, before or during interrupt processing for an interrupt
event already detected on this interrupt input. The IPEND register contents are monitored by the SIC as the interrupt
acknowledgement.
The appropriate ILAT register bit is set when an interrupt rising
edge is detected (detection requires two core clock cycles). The
bit is cleared when the respective IPEND register bit is set. The
IPEND bit indicates that the event has entered into the processor pipeline. At this point the CEC will recognize and queue the
next rising edge event on the corresponding event input. The
minimum latency from the rising edge transition of the generalpurpose interrupt to the IPEND output asserted is three core
clock cycles; however, the latency can be much higher, depending on the activity within and the mode of the processor.
DMA CONTROLLERS
The ADSP-BF561 has multiple, independent DMA controllers
that support automated data transfers with minimal overhead
for the DSP core. DMA transfers can occur between the
ADSP-BF561 internal memories and any of its DMA-capable
peripherals. Additionally, DMA transfers can be accomplished
between any of the DMA-capable peripherals and external
devices connected to the external memory interfaces, including
the SDRAM controller and the asynchronous memory controlRev. A |
The ADSP-BF561 DMA controllers support both 1-dimensional (1-D) and 2-dimensional (2-D) DMA transfers. DMA
transfer initialization can be implemented from registers or
from sets of parameters called descriptor blocks.
The 2-D DMA capability supports arbitrary row and column
sizes up to 64K elements by 64K elements, and arbitrary row
and column step sizes up to ± 32K elements. Furthermore, the
column step size can be less than the row step size, allowing
implementation of interleaved data streams. This feature is
especially useful in video applications where data can be deinterleaved on the fly.
Examples of DMA types supported by the ADSP-BF561 DMA
controllers include:
• A single linear buffer that stops upon completion.
• A circular autorefreshing buffer that interrupts on each full
or fractionally full buffer.
• 1-D or 2-D DMA using a linked list of descriptors.
• 2-D DMA using an array of descriptors, specifying only the
base DMA address within a common page.
In addition to the dedicated peripheral DMA channels, each
DMA Controller has four memory DMA channels provided for
transfers between the various memories of the ADSP-BF561
system. These enable transfers of blocks of data between any of
the memories—including external SDRAM, ROM, SRAM, and
flash memory—with minimal processor intervention. Memory
DMA transfers can be controlled by a very flexible descriptorbased methodology or by a standard register-based autobuffer
mechanism.
Further, the ADSP-BF561 has a four channel Internal Memory
DMA (IMDMA) Controller. The IMDMA Controller allows
data transfers between any of the internal L1 and L2 memories.
WATCHDOG TIMER
Each ADSP-BF561 core includes a 32-bit timer, which can be
used to implement a software watchdog function. A software
watchdog can improve system availability by forcing the processor to a known state, via generation of a hardware reset,
nonmaskable interrupt (NMI), or general-purpose interrupt, if
the timer expires before being reset by software. The programmer initializes the count value of the timer, enables the
appropriate interrupt, then enables the timer. Thereafter, the
software must reload the counter before it counts to zero from
the programmed value. This protects the system from remaining in an unknown state where software, which would normally
reset the timer, has stopped running due to an external noise
condition or software error.
After a reset, software can determine if the watchdog was the
source of the hardware reset by interrogating a status bit in the
timer control register, which is set only upon a watchdog generated reset.

ADSP-BF561
The timer is clocked by the system clock (SCLK) at a maximum
frequency of fSCLK.
• Interrupts – Each transmit and receive port generates an
interrupt upon completing the transfer of a data word or
after transferring an entire data buffer or buffers through
DMA.
TIMERS
There are 14 programmable timer units in the ADSP-BF561.
Each of the 12 general-purpose timer units can be independently programmed as a Pulse-Width Modulator (PWM),
internally or externally clocked timer, or pulse-width counter.
The general-purpose timer units can be used in conjunction
with the UART to measure the width of the pulses in the data
stream to provide an autobaud detect function for a serial channel. The general-purpose timers can generate interrupts to the
processor core providing periodic events for synchronization,
either to the processor clock or to a count of external signals.
In addition to the 12 general-purpose programmable timers,
another timer is also provided for each core. These extra timers
are clocked by the internal processor clock (CCLK) and are typically used as a system tick clock for generation of operating
system periodic interrupts.
SERIAL PORTS (SPORTs)
The ADSP-BF561 incorporates two dual-channel synchronous
serial ports (SPORT0 and SPORT1) for serial and multiprocessor communications. The SPORTs support the following
features:
• I2S capable operation.
• Bidirectional operation – Each SPORT has two sets of independent transmit and receive pins, enabling eight channels
of I2S stereo audio.
• Buffered (8-deep) transmit and receive ports – Each port
has a data register for transferring data words to and from
other DSP components and shift registers for shifting data
in and out of the data registers.
• Clocking – Each transmit and receive port can either use an
external serial clock or generate its own, in frequencies
ranging from (fSCLK/131,070) Hz to (fSCLK/2) Hz.
• Word length – Each SPORT supports serial data words
from 3 bits to 32 bits in length, transferred most significant
bit first or least significant bit first.
• Framing – Each transmit and receive port can run with or
without frame sync signals for each data word. Frame sync
signals can be generated internally or externally, active high
or low, and with either of two pulse-widths and early or late
frame sync.
• Companding in hardware – Each SPORT can perform
A-law or µ-law companding according to ITU recommendation G.711. Companding can be selected on the transmit
and/or receive channel of the SPORT without additional
latencies.
• Multichannel capability – Each SPORT supports 128 channels out of a 1,024-channel window and is compatible with
the H.100, H.110, MVIP-90, and HMVIP standards.
SERIAL PERIPHERAL INTERFACE (SPI) PORT
The ADSP-BF561 processor has an SPI-compatible port that
enables the processor to communicate with multiple SPI-compatible devices.
The SPI interface uses three pins for transferring data: two data
pins (master output-slave input, MOSI, and master input-slave
output, MISO) and a clock pin (serial clock, SCK). An SPI chip
select input pin (SPISS) lets other SPI devices select the processor, and seven SPI chip select output pins (SPISEL7–1) let the
processor select other SPI devices. The SPI select pins are reconfigured programmable flag pins. Using these pins, the SPI port
provides a full-duplex, synchronous serial interface which supports both master/slave modes and multimaster environments.
The baud rate and clock phase/polarities for the SPI port are
programmable, and it has an integrated DMA controller, configurable to support transmit or receive data streams. The SPI
DMA controller can only service unidirectional accesses at any
given time.
The SPI port clock rate is calculated as:
f SCLK
SPI Clock Rate = -------------------------------2 × SPI_Baud
Where the 16-bit SPI_Baud register contains a value of 2 to
65,535.
During transfers, the SPI port simultaneously transmits and
receives by serially shifting data in and out on its two serial data
lines. The serial clock line synchronizes the shifting and sampling of data on the two serial data lines.
UART PORT
The ADSP-BF561 processor provides a full-duplex universal
asynchronous receiver/transmitter (UART) port, which is fully
compatible with PC-standard UARTs. The UART port provides
a simplified UART interface to other peripherals or hosts, supporting full-duplex, DMA-supported, asynchronous transfers of
serial data. The UART port includes support for 5 data bits to
8 data bits, 1 stop bit or 2 stop bits, and none, even, or odd parity. The UART port supports two modes of operation:
• DMA operations with single-cycle overhead – Each SPORT
can automatically receive and transmit multiple buffers of
memory data. The DSP can link or chain sequences of
DMA transfers between a SPORT and memory.
Rev. A |
Page 10 of 60 |
• PIO (programmed I/O) – The processor sends or receives
data by writing or reading I/O-mapped UART registers.
The data is double-buffered on both transmit and receive.
• DMA (direct memory access) – The DMA controller transfers both transmit and receive data. This reduces the
number and frequency of interrupts required to transfer
data to and from memory. The UART has two dedicated

defined as inputs can be configured to generate hardware
interrupts, while output PFx pins can be configured to generate software interrupts.
DMA channels, one for transmit and one for receive. These
DMA channels have lower default priority than most DMA
channels because of their relatively low service rates.
• Flag Interrupt Sensitivity Registers – The Flag Interrupt
Sensitivity Registers specify whether individual PFx pins
are level- or edge-sensitive and specify, if edge-sensitive,
whether just the rising edge or both the rising and falling
edges of the signal are significant. One register selects the
type of sensitivity, and one register selects which edges are
significant for edge sensitivity.
The baud rate, serial data format, error code generation and status, and interrupts for the UART port are programmable.
The UART programmable features include:
• Supporting bit rates ranging from (fSCLK/1,048,576) bits per
second to (fSCLK/16) bits per second.
• Supporting data formats from seven bits to 12 bits per
frame.
• Both transmit and receive operations can be configured to
generate maskable interrupts to the processor.
The UART port’s clock rate is calculated as:
f SCLK
UART Clock Rate = ----------------------------------------------16 × UART_Divisor
Where the 16-bit UART_Divisor comes from the DLH register
(most significant 8 bits) and DLL register (least significant
8 bits).
In conjunction with the general-purpose timer functions,
autobaud detection is supported.
The capabilities of the UART are further extended with support
for the Infrared Data Association (IrDA) serial infrared physical
layer link specification (SIR) protocol.
PARALLEL PERIPHERAL INTERFACE
The ADSP-BF561 processor provides two parallel peripheral
interfaces (PPI0, PPI1) that can connect directly to parallel A/D
and D/A converters, ITU-R 601/656 video encoders and decoders, and other general-purpose peripherals. Each PPI consists of
a dedicated input clock pin, up to three frame synchronization
pins, and up to 16 data pins. The input clock supports parallel
data rates up to half the system clock rate.
In ITU-R 656 modes, the PPI receives and parses a data stream
of 8-bit or 10-bit data elements. On-chip decode of embedded
preamble control and synchronization information is
supported.
Three distinct ITU-R 656 modes are supported:
• Active video only – The PPI does not read in any data
between the end of active video (EAV) and start of active
video (SAV) preamble symbols, or any data present during
the vertical blanking intervals. In this mode, the control
byte sequences are not stored to memory; they are filtered
by the PPI.
PROGRAMMABLE FLAGS (PFx)
The ADSP-BF561 has 48 bidirectional, general-purpose I/O,
programmable flag (PF47–0) pins. The programmable flag pins
have special functions for SPI port operation. Each programmable flag can be individually controlled by manipulation of the
flag control, status, and interrupt registers as follows:
• Vertical blanking only – The PPI only transfers vertical
blanking interval (VBI) data, as well as horizontal blanking
information and control byte sequences on VBI lines.
• Flag Direction Control Register – Specifies the direction of
each individual PFx pin as input or output.
• Flag Control and Status Registers – Rather than forcing the
software to use a read-modify-write process to control the
setting of individual flags, the ADSP-BF561 employs a
“write one to set” and “write one to clear” mechanism that
allows any combination of individual flags to be set or
cleared in a single instruction, without affecting the level of
any other flags. Two control registers are provided, one
register is written-to in order to set flag values, while
another register is written-to in order to clear flag values.
Reading the flag status register allows software to interrogate the sense of the flags.
• Flag Interrupt Mask Registers – The Flag Interrupt Mask
Registers allow each individual PFx pin to function as an
interrupt to the processor. Similar to the Flag Control Registers that are used to set and clear individual flag values,
one Flag Interrupt Mask Register sets bits to enable an
interrupt function, and the other Flag Interrupt Mask Register clears bits to disable an interrupt function. PFx pins
• Entire field – The entire incoming bitstream is read in
through the PPI. This includes active video, control preamble sequences, and ancillary data that may be embedded in
horizontal and vertical blanking intervals.
Though not explicitly supported, ITU-R 656 output functionality can be achieved by setting up the entire frame structure
(including active video, blanking, and control information) in
memory and streaming the data out the PPI in a frame sync-less
mode. The processor’s 2-D DMA features facilitate this transfer
by allowing the static frame buffer (blanking and control codes)
to be placed in memory once, and simply updating the active
video information on a per-frame basis.
The general-purpose modes of the PPI are intended to suit a
wide variety of data capture and transmission applications. The
modes are divided into four main categories, each allowing up
to 16 bits of data transfer per PPI_CLK cycle:
• Data receive with internally generated frame syncs
• Data receive with externally generated frame syncs
• Data transmit with internally generated frame syncs
• Data transmit with externally generated frame syncs

ADSP-BF561
These modes support ADC/DAC connections, as well as video
communication with hardware signaling. Many of the modes
support more than one level of frame synchronization. If
desired, a programmable delay can be inserted between assertion of a frame sync and reception/transmission of data.
DYNAMIC POWER MANAGEMENT
The ADSP-BF561 provides four power management modes and
one power management state, each with a different performance/power profile. In addition, Dynamic Power
Management provides the control functions to dynamically
alter the processor core supply voltage, further reducing power
dissipation. Control of clocking to each of the ADSP-BF561
peripherals also reduces power consumption. See Table 3 for a
summary of the power settings for each mode.

Full-On Operating Mode—Maximum Performance
In the Full-On mode, the PLL is enabled and is not bypassed,
providing capability for maximum operational frequency. This
is the default execution state in which maximum performance
can be achieved. The processor cores and all enabled peripherals
run at full speed.
Active Operating Mode—Moderate Power Savings
In the Active mode, the PLL is enabled but bypassed. Because
the PLL is bypassed, the processor’s core clock (CCLK) and system clock (SCLK) run at the input clock (CLKIN) frequency. In
this mode, the CLKIN to CCLK multiplier ratio can be changed,
although the changes are not realized until the Full-On mode is
entered. DMA access is available to appropriately configured L1
and L2 memories.
In the Active mode, it is possible to disable the PLL through the
PLL Control Register (PLL_CTL). If disabled, the PLL must be
re-enabled before transitioning to the Full-On or Sleep modes.
Sleep Operating Mode—High Dynamic Power Savings
The Sleep mode reduces power dissipation by disabling the
clock to the processor core (CCLK). The PLL and system clock
(SCLK), however, continue to operate in this mode. Typically an
external event will wake up the processor. When in the Sleep
mode, assertion of wakeup will cause the processor to sense the
value of the BYPASS bit in the PLL Control register (PLL_CTL).
When in the Sleep mode, system DMA access is only available
to external memory, not to L1 or on-chip L2 memory.
Rev. A |
Deep Sleep Operating Mode—Maximum Dynamic Power
Savings
The Deep Sleep mode maximizes power savings by disabling the
clocks to the processor cores (CCLK) and to all synchronous
peripherals (SCLK). Asynchronous peripherals will not be able
to access internal resources or external memory. This powereddown mode can only be exited by assertion of the reset interrupt
(RESET). If BYPASS is disabled, the processor will transition to
the Full-On mode. If BYPASS is enabled, the processor will
transition to the Active mode.
Hibernate Operating State—Maximum Static Power
Savings
The Hibernate state maximizes static power savings by disabling
the voltage and clocks to the processor core (CCLK) and to all
the synchronous peripherals (SCLK). The internal voltage regulator for the processor can be shut off by writing b#00 to the
FREQ bits of the VR_CTL register. This disables both CCLK
and SCLK. Furthermore, it sets the internal power supply voltage (VDDINT) to 0 V to provide the lowest static power dissipation.
Any critical information stored internally (memory contents,
register contents, etc.) must be written to a nonvolatile storage
device prior to removing power if the processor state is to be
preserved. Since VDDEXT is still supplied in this mode, all of the
external pins three-state, unless otherwise specified. This allows
other devices that may be connected to the processor to have
power still applied without drawing unwanted current. The
internal supply regulator can be woken up by asserting the
RESET pin.
Power Savings
As shown in Table 4, the ADSP-BF561 supports two different
power domains. The use of multiple power domains maximizes
flexibility, while maintaining compliance with industry standards and conventions. By isolating the internal logic of the
ADSP-BF561 into its own power domain, separate from the I/O,
the processor can take advantage of Dynamic Power Management, without affecting the I/O devices. There are no
sequencing requirements for the various power domains.

The power dissipated by a processor is largely a function of the
clock frequency of the processor and the square of the operating
voltage. For example, reducing the clock frequency by 25%
results in a 25% reduction in dynamic power dissipation, while
reducing the voltage by 25% reduces dynamic power dissipation
by more than 40%. Further, these power savings are additive, in
that if the clock frequency and supply voltage are both reduced,
the power savings can be dramatic.
The Dynamic Power Management feature of the ADSP-BF561
allows both the processor’s input voltage (VDDINT) and clock frequency (fCCLK) to be dynamically controlled.

CLOCK SIGNALS
The savings in power dissipation can be modeled using the
power savings factor and % power savings calculations.
The ADSP-BF561 can be clocked by an external crystal, a sine
wave input, or a buffered, shaped clock derived from an external
clock oscillator.
The power savings factor is calculated as:
power savings factor
If an external clock is used, it should be a TTL-compatible signal
and must not be halted, changed, or operated below the specified frequency during normal operation. This signal is
connected to the processor CLKIN pin. When an external clock
is used, the XTAL pin must be left unconnected.

- × -------------------------- × ------------= -------------------⎝ T NOM ⎠
f CCLKNOM ⎝ V DDINTNOM⎠
where the variables in the equations are:
fCCLKNOM is the nominal core clock frequency
Alternatively, because the ADSP-BF561 includes an on-chip
oscillator circuit, an external crystal may be used. The crystal
should be connected across the CLKIN and XTAL pins, with
two capacitors connected as shown in Figure 5.
fCCLKRED is the reduced core clock frequency
VDDINTNOM is the nominal internal supply voltage
VDDINTRED is the reduced internal supply voltage
Capacitor values are dependent on crystal type and should be
specified by the crystal manufacturer. A parallel-resonant, fundamental frequency, microprocessor-grade crystal should be
used.
TNOM is the duration running at fCCLKNOM
TRED is the duration running at fCCLKRED
The percent power savings is calculated as:
% power savings = ( 1 – power savings factor ) × 100%
VOLTAGE REGULATION
The ADSP-BF561 processor provides an on-chip voltage regulator that can generate processor core voltage levels 0.85 V to
1.25 V from an external 2.25 V to 3.6 V supply. Figure 4 shows
the typical external components required to complete the power
management system. The regulator controls the internal logic
voltage levels and is programmable with the Voltage Regulator
Control Register (VR_CTL) in increments of 50 mV. To reduce
standby power consumption, the internal voltage regulator can
be programmed to remove power to the processor core while
keeping I/O power (VDDEXT) supplied. While in the hibernate
state VDDEXT can still be applied, eliminating the need for external
buffers. The voltage regulator can be activated from this powerdown state by asserting RESET, which will then initiate a boot
sequence. The regulator can also be disabled and bypassed at the
user’s discretion.
CLKIN

Figure 5. External Crystal Connections
As shown in Figure 6, the core clock (CCLK) and system
peripheral clock (SCLK) are derived from the input clock
(CLKIN) signal. An on-chip PLL is capable of multiplying the
CLKIN signal by a user-programmable 0.5× to 64× multiplication factor. The default multiplier is 10×, but it can be modified
by a software instruction sequence. On the fly frequency
changes can be effected by simply writing to the PLL_DIV
register.

BOOTING MODES
The ADSP-BF561 has three mechanisms (listed in Table 7) for
automatically loading internal L1 instruction memory or L2
after a reset. A fourth mode is provided to execute from external
memory, bypassing the boot sequence.
Table 7. Booting Modes
BMODE1–0

The maximum frequency of the system clock is fSCLK. Note that
the divisor ratio must be chosen to limit the system clock frequency to its maximum of fSCLK. The SSEL value can be changed
dynamically without any PLL lock latencies by writing the
appropriate values to the PLL divisor register (PLL_DIV).
The core clock (CCLK) frequency can also be dynamically
changed by means of the CSEL1–0 bits of the PLL_DIV register.
Supported CCLK divider ratios are 1, 2, 4, and 8, as shown in
Table 6. This programmable core clock capability is useful for
fast core frequency modifications.

The BMODE pins of the Reset Configuration Register, sampled
during power-on resets and software initiated resets, implement
the following modes:
• Execute from 16-bit external memory – Execution starts
from address 0x2000 0000 with 16-bit packing. The boot
ROM is bypassed in this mode. All configuration settings
are set for the slowest device possible (3-cycle hold time,

The maximum PLL clock time when a change is programmed
via the PLL_CTL register is 40 µs. The maximum time to change
the internal voltage via the internal voltage regulator is also
40 µs. The reset value for the PLL_LOCKCNT register is 0x200.
This value should be programmed to ensure a 40 µs wakeup
time when either the voltage is changed or a new MSEL value is
programmed. The value should be programmed to ensure an
80 µs wakeup time when both voltage and the MSEL value are
changed. The time base for the PLL_LOCKCNT register is the
period of CLKIN.
• Boot from SPI serial EEPROM (16-bit addressable) – The
SPI uses the PF2 output pin to select a single SPI EPROM
device, submits a read command at address 0x0000, and
begins clocking data into the beginning of L1 instruction
memory. A 16-bit addressable SPI-compatible EPROM
must be used.
For each of the boot modes, a boot loading protocol is used to
transfer program and data blocks from an external memory
device to their specified memory locations. Multiple memory
blocks may be loaded by any boot sequence. Once all blocks are
loaded, Core A program execution commences from the start of
L1 instruction SRAM (0xFFA0 0000). Core B remains in a heldoff state until Bit 5 of SICA_SYSCR is cleared. After that, Core B
will start execution at address 0xFF60 0000.
In addition, Bit 4 of the Reset Configuration Register can be set
by application code to bypass the normal boot sequence during
a software reset. For this case, the processor jumps directly to
the beginning of L1 instruction memory.

employs an algebraic syntax that was designed for ease of coding
and readability. The instructions have been specifically tuned to

vides fully featured multifunction instructions that allow the
programmer to use many of the processor core resources in a
single instruction. Coupled with many features more often seen
on microcontrollers, this instruction set is very efficient when
compiling C and C++ source code. In addition, the architecture
supports both a user (algorithm/application code) and a supervisor (O/S kernel, device drivers, debuggers, ISRs) mode of
operation—allowing multiple levels of access to core processor
resources.
The assembly language, which takes advantage of the processor’s unique architecture, offers the following advantages:
• Seamlessly integrated DSP/CPU features are optimized for
both 8-bit and 16-bit operations.
designer’s development schedule, increasing productivity. Statistical profiling enables the programmer to nonintrusively poll
the processor as it is running the program. This feature, unique
to VisualDSP++, enables the software developer to passively
gather important code execution metrics without interrupting
the real-time characteristics of the program. Essentially, the
developer can identify bottlenecks in software quickly and efficiently. By using the profiler, the programmer can focus on
those areas in the program that impact performance and take
corrective action.
Debugging both C/C++ and assembly programs with the
VisualDSP++ debugger, programmers can:
• View mixed C/C++ and assembly code (interleaved source
and object information).
• A multi-issue load/store modified Harvard architecture,
which supports two 16-bit MAC or four 8-bit ALU plus
two load/store plus two pointer updates per cycle.
• Insert breakpoints.
• Set conditional breakpoints on registers, memory, and
stacks.
• All registers, I/O, and memory are mapped into a unified
4G byte memory space providing a simplified programming model.
• Trace instruction execution.

• Code density enhancements, which include intermixing of
16-bit and 32-bit instructions (no mode switching, no code
segregation). Frequently used instructions are encoded as
16-bits.
DEVELOPMENT TOOLS
The ADSP-BF561 is supported with a complete set of
CROSSCORE®† software and hardware development tools,
including Analog Devices emulators and the VisualDSP++®‡
development environment. The same emulator hardware that
supports other Analog Devices processors also fully emulates
the ADSP-BF561.
The VisualDSP++ project management environment lets programmers develop and debug an application. This environment
includes an easy to use assembler that is based on an algebraic
syntax, an archiver (librarian/library builder), a linker, a loader,
a cycle-accurate instruction-level simulator, a C/C++ compiler,
and a C/C++ runtime library that includes DSP and mathematical functions. A key point for these tools is C/C++ code
efficiency. The compiler has been developed for efficient translation of C/C++ code to Blackfin assembly. The Blackfin
processor has architectural features that improve the efficiency
of compiled C/C++ code.
The VisualDSP++ debugger has a number of important features. Data visualization is enhanced by a plotting package that
offers a significant level of flexibility. This graphical representation of user data enables the programmer to quickly determine
the performance of an algorithm. As algorithms grow in complexity, this capability can have increasing significance on the
†
‡
• Fill, dump, and graphically plot the contents of memory.
• Perform source level debugging.
• Create custom debugger windows.
The VisualDSP++ IDE lets programmers define and manage
software development. Its dialog boxes and property pages let
programmers configure and manage all development tools,
including Color Syntax Highlighting in the VisualDSP++
editor. These capabilities permit programmers to:
• Control how the development tools process inputs and
generate outputs.
• Maintain a one-to-one correspondence with the tool’s
command line switches.
The VisualDSP++ Kernel (VDK) incorporates scheduling and
resource management tailored specifically to address the memory and timing constraints of embedded, real-time
programming. These capabilities enable engineers to develop
code more effectively, eliminating the need to start from the
very beginning when developing new application code. The
VDK features include threads, critical and unscheduled regions,
semaphores, events, and device flags. The VDK also supports
priority-based, pre-emptive, cooperative, and time-sliced
scheduling approaches. In addition, the VDK was designed to
be scalable. If the application does not use a specific feature, the
support code for that feature is excluded from the target system.
Because the VDK is a library, a developer can decide whether to
use it or not. The VDK is integrated into the VisualDSP++
development environment, but can also be used with standard
command line tools. When the VDK is used, the development
environment assists the developer with many error prone tasks
and assists in managing system resources, automating the
generation of various VDK-based objects, and visualizing the
system state when debugging an application that uses the VDK.

ADSP-BF561
VCSE is Analog Devices’ technology for creating, using, and
reusing software components (independent modules of substantial functionality) to quickly and reliably assemble software
applications. Components can be downloaded from the Web
and dropped into the application. Component archives can be
published from within VisualDSP++. VCSE supports component implementation in C/C++ or assembly language.
The Expert Linker can be used to visually manipulate the placement of code and data in the embedded system. Memory
utilization can be viewed in a color-coded graphical form. Code
and data can be easily moved to different areas of the processor
or external memory with the drag of the mouse. Runtime stack
and heap usage can be examined. The Expert Linker is fully
compatible with existing Linker Definition File (LDF), allowing
the developer to move between the graphical and textual
environments.

to keep pace with improvements to emulator support.
RELATED DOCUMENTS
The following publications that describe the ADSP-BF561 processors (and related processors) can be ordered from any
Analog Devices sales office or accessed electronically on our
website:

• ADSP-BF561 Blackfin Processor Hardware Reference
• ADSP-BF53x/BF56x Blackfin Processor Programming
Reference
• ADSP-BF561 Blackfin Processor Anomaly List
Analog Devices emulators use the IEEE 1149.1 JTAG test access
port of the ADSP-BF561 to monitor and control the target
board processor during emulation. The emulator provides fullspeed emulation, allowing inspection and modification of memory, registers, and processor stacks. Nonintrusive in-circuit
emulation is assured by the use of the processor’s JTAG interface—the emulator does not affect the loading or timing of the
target system.
In addition to the software and hardware development tools
available from Analog Devices, third parties provide a wide
range of tools supporting the Blackfin processor family. Third
party software tools include DSP libraries, real-time operating
systems, and block diagram design tools.
EZ-KIT Lite Evaluation Board
For evaluation of ADSP-BF561 processors, use the
ADSP-BF561 EZ-KIT Lite® board available from Analog
Devices. Order part number ADDS-BF561-EZLITE. The board
comes with on-chip emulation capabilities and is equipped to
enable software development. Multiple daughter cards are
available.
DESIGNING AN EMULATOR-COMPATIBLE
PROCESSOR BOARD (TARGET)
The Analog Devices family of emulators are tools that every system developer needs to test and debug hardware and software
systems. Analog Devices has supplied an IEEE 1149.1 JTAG
Test Access Port (TAP) on the ADSP-BF561. The emulator uses
the TAP to access the internal features of the processor, allowing the developer to load code, set breakpoints, observe
variables, observe memory, and examine registers. The processor must be halted to send data and commands, but once an
operation has been completed by the emulator, the processor is
set running at full speed with no impact on system timing.
To use these emulators, the target board must include a header
that connects the processor’s JTAG port to the emulator.
For details on target board design issues, including mechanical
layout, single processor connections, multiprocessor scan
chains, signal buffering, signal termination, and emulator pod
logic, see EE-68: Analog Devices JTAG Emulation Technical

ESD SENSITIVITY
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate
on the human body and test equipment and can discharge without detection. Although the ADSP-BF561
features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high
energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.

Many operating conditions can affect power dissipation. System
designers should refer to EE-293: Estimating Power for ADSPBF561 Blackfin Processors on the Analog Devices website
(www.analog.com)—use site search on “EE-293.” This document provides detailed information for optimizing your design
for lowest power.

ADSP-BF561
TEST CONDITIONS
Example System Hold Time Calculation
All timing parameters appearing in this data sheet were measured under the conditions described in this section. Figure 34
shows the measurement point for ac measurements (except output enable/disable). The measurement point VMEAS is 1.5 V for
VDDEXT (nominal) = 2.5 V/3.3 V.
To determine the data output hold time in a particular system,
first calculate tDECAY using the equation given above. Choose ∆V
to be the difference between the ADSP-BF561 processor’s output voltage and the input threshold for the device requiring the
hold time. CL is the total bus capacitance (per data line), and IL is
the total leakage or three-state current (per data line). The hold
time will be tDECAY plus the various output disable times as specified in the Timing Specifications on Page 22 (for example tDSDAT
for an SDRAM write cycle as shown in SDRAM Interface Timing on Page 26).

The time tENA_MEASURED is the interval, from when the reference signal switches, to when the output voltage reaches VTRIP(high) or
VTRIP(low). VTRIP(high) is 2.0 V and VTRIP(low) is 1.0 V for VDDEXT
(nominal) = 2.5 V/3.3 V. Time tTRIP is the interval from when the
output starts driving to when the output reaches the VTRIP(high)
or VTRIP(low) trip voltage.

If multiple pins (such as the data bus) are enabled, the measurement value is that of the first pin to start driving.
Figure 36. Equivalent Device Loading for AC Measurements
(Includes All Fixtures)
Output Disable Time Measurement
Output pins are considered to be disabled when they stop driving, go into a high impedance state, and start to decay from their
output high or low voltage. The output disable time tDIS is the
difference between tDIS_MEASURED and tDECAY as shown on the left side
of Figure 35.
t DIS = t DIS_MEASURED – t DECAY
The time for the voltage on the bus to decay by ∆V is dependent
on the capacitive load CL and the load current IL. This decay time
can be approximated by the equation:
Capacitive Loading
Output delays and holds are based on standard capacitive loads:
30 pF on all pins (see Figure 36). VLOAD is 1.5 V for VDDEXT (nominal) = 2.5 V/3.3 V. Figure 37 on Page 44 through Figure 44 on
Page 45 show how output rise time varies with capacitance. The
delay and hold specifications given should be derated by a factor
derived from these figures. The graphs in these figures may not
be linear outside the ranges shown.
t DECAY = ( C L ∆V ) ⁄ I L
The time tDECAY is calculated with test loads CL and IL, and with
∆V equal to 0.5 V for VDDEXT (nominal) = 2.5 V/3.3 V.
The time tDIS_MEASURED is the interval from when the reference signal switches, to when the output voltage decays ∆V from the
measured output high or output low voltage.
