ADSP-21000 FAMILY CORE ARCHITECTURE
Instruction Cache
The ADSP-2106x includes the following architectural features
of the ADSP-21000 family core. The ADSP-21060C is codeand function-compatible with the ADSP-21061 and ADSP-21062.
The ADSP-2106x includes an on-chip instruction cache that
enables three-bus operation for fetching an instruction and two
data values. The cache is selective—only the instructions whose
fetches conflict with PM bus data accesses are cached. This
allows full-speed execution of core, looped operations such as
digital filter multiply-accumulates and FFT butterfly processing.
Independent, Parallel Computation Units
The arithmetic/logic unit (ALU), multiplier and shifter all perform single-cycle instructions. The three units are arranged in
parallel, maximizing computational throughput. Single multifunction instructions execute parallel ALU and multiplier operations. These computation units support IEEE 32-bit singleprecision floating-point, extended precision 40-bit floatingpoint, and 32-bit fixed-point data formats.

Data Address Generators with Hardware Circular Buffers
The ADSP-2106x’s two data address generators (DAGs) implement circular data buffers in hardware. Circular buffers allow
efficient programming of delay lines and other data structures
required in digital signal processing, and are commonly used in
digital filters and Fourier transforms. The two DAGs of the
ADSP-2106x contain sufficient registers to allow the creation of
up to 32 circular buffers (16 primary register sets, 16 secondary). The DAGs automatically handle address pointer wraparound, reducing overhead, increasing performance, and
simplifying implementation. Circular buffers can start and end
at any memory location.
Flexible Instruction Set
The 48-bit instruction word accommodates a variety of parallel
operations, for concise programming. For example, the ADSP2106x can conditionally execute a multiply, an add, a subtract
and a branch, all in a single instruction.

ADSP-21060C/ADSP-21060LC FEATURES
Augmenting the ADSP-21000 family core, the ADSP-21060
adds the following architectural features:

PROCESSOR
INTERFACE
(OPTIONAL)
The ADSP-21060C contains four megabits of on-chip SRAM,
organized as two blocks of 2 Mbits each, which can be configured for different combinations of code and data storage.
Each memory block is dual-ported for single-cycle, independent
accesses by the core processor and I/O processor or DMA controller. The dual-ported memory and separate on-chip buses
allow two data transfers from the core and one from I/O, all in a
single cycle.

DATA

Figure 2. ADSP-2106x System
On the ADSP-21060C, the memory can be configured as a
maximum of 128K words of 32-bit data, 256K words of 16-bit
data, 80K words of 48-bit instructions (or 40-bit data), or combinations of different word sizes up to four megabits. All of
the memory can be accessed as 16-bit, 32-bit, or 48-bit words.
Data Register File
A general purpose data register file is used for transferring data
between the computation units and the data buses, and for
storing intermediate results. This 10-port, 32-register (16 primary, 16 secondary) register file, combined with the ADSP21000 Harvard architecture, allows unconstrained data flow
between computation units and internal memory.
A 16-bit floating-point storage format is supported that effectively doubles the amount of data that may be stored on-chip.
Conversion between the 32-bit floating-point and 16-bit floatingpoint formats is done in a single instruction.
Single-Cycle Fetch of Instruction and Two Operands
The ADSP-2106x features an enhanced Harvard architecture in
which the data memory (DM) bus transfers data and the program memory (PM) bus transfers both instructions and data
(see Figure 1). With its separate program and data memory
buses and on-chip instruction cache, the processor can simultaneously fetch two operands and an instruction (from the cache),
all in a single cycle.
While each memory block can store combinations of code and
data, accesses are most efficient when one block stores data,
using the DM bus for transfers, and the other block stores
instructions and data, using the PM bus for transfers. Using the
DM bus and PM bus in this way, with one dedicated to each
memory block, assures single-cycle execution with two data
transfers. In this case, the instruction must be available in the
cache. Single-cycle execution is also maintained when one of the
data operands is transferred to or from off-chip, via the ADSP2106x’s external port.

ADSP-21060C/ADSP-21060LC
Off-Chip Memory and Peripherals Interface
Serial Ports
The ADSP-2106x’s external port provides the processor’s interface to off-chip memory and peripherals. The 4-gigaword offchip address space is included in the ADSP-2106x’s unified
address space. The separate on-chip buses—for PM addresses,
PM data, DM addresses, DM data, I/O addresses, and I/O
data—are multiplexed at the external port to create an external
system bus with a single 32-bit address bus and a single 48-bit
(or 32-bit) data bus.
The ADSP-2106x features two synchronous serial ports that
provide an inexpensive interface to a wide variety of digital and
mixed-signal peripheral devices. The serial ports can operate at
the full clock rate of the processor, providing each with a maximum data rate of 40 Mbit/s. Independent transmit and receive
functions provide greater flexibility for serial communications.
Serial port data can be automatically transferred to and from
on-chip memory via DMA. Each of the serial ports offers TDM
multichannel mode.
Addressing of external memory devices is facilitated by on-chip
decoding of high-order address lines to generate memory bank
select signals. Separate control lines are also generated for simplified addressing of page-mode DRAM. The ADSP-2106x
provides programmable memory wait states and external
memory acknowledge controls to allow interfacing to DRAM
and peripherals with variable access, hold, and disable time
requirements.
Host Processor Interface
The ADSP-2106x’s host interface allows easy connection to
standard microprocessor buses, both 16-bit and 32-bit, with
little additional hardware required. Asynchronous transfers at
speeds up to the full clock rate of the processor are supported.
The host interface is accessed through the ADSP-2106x’s external port and is memory-mapped into the unified address space.
Four channels of DMA are available for the host interface; code
and data transfers are accomplished with low software overhead.
The host processor requests the ADSP-2106x’s external bus
with the host bus request (HBR), host bus grant (HBG), and
ready (REDY) signals. The host can directly read and write the
internal memory of the ADSP-2106x, and can access the DMA
channel setup and mailbox registers. Vector interrupt support is
provided for efficient execution of host commands.
DMA Controller
The ADSP-2106x’s on-chip DMA controller allows zerooverhead data transfers without processor intervention. The
DMA controller operates independently and invisibly to the
processor core, allowing DMA operations to occur while the
core is simultaneously executing its program instructions.
DMA transfers can occur between the ADSP-2106x’s internal
memory and either external memory, external peripherals or a
host processor. DMA transfers can also occur between the
ADSP-2106x’s internal memory and its serial ports or link
ports. DMA transfers between external memory and external
peripheral devices are another option. External bus packing to
16-, 32-, or 48-bit words is performed during DMA transfers.
Ten channels of DMA are available on the ADSP-2106x—two
via the link ports, four via the serial ports, and four via the
processor’s external port (for either host processor, other
ADSP-2106xs, memory or I/O transfers). Four additional link
port DMA channels are shared with serial port 1 and the external port. Programs can be downloaded to the ADSP-2106x
using DMA transfers. Asynchronous off-chip peripherals can
control two DMA channels using DMA Request/Grant lines
(DMAR1-2, DMAG1-2 ). Other DMA features include interrupt generation upon completion of DMA transfers and DMA
chaining for automatic linked DMA transfers.
REV. B
The serial ports can operate with little-endian or big-endian
transmission formats, with word lengths selectable from 3 bits to
32 bits. They offer selectable synchronization and transmit
modes as well as optional µ-law or A-law companding. Serial
port clocks and frame syncs can be internally or externally
generated.
Multiprocessing
The ADSP-2106x offers powerful features tailored to multiprocessing DSP systems. The unified address space (see
Figure 4) allows direct interprocessor accesses of each ADSP2106x’s internal memory. Distributed bus arbitration logic is
included on-chip for simple, glueless connection of systems
containing up to six ADSP-2106xs and a host processor. Master
processor changeover incurs only one cycle of overhead. Bus
arbitration is selectable as either fixed or rotating priority. Bus lock
allows indivisible read-modify-write sequences for semaphores. A
vector interrupt is provided for interprocessor commands. Maximum throughput for interprocessor data transfer is 240 Mbytes/s
over the link ports or external port. Broadcast writes allow simultaneous transmission of data to all ADSP-2106xs and can be used
to implement reflective semaphores.
Link Ports
The ADSP-2106x features six 4-bit link ports that provide additional I/O capabilities. The link ports can be clocked twice per
cycle, allowing each to transfer eight bits per cycle. Link port
I/O is especially useful for point-to-point interprocessor communication in multiprocessing systems.
The link ports can operate independently and simultaneously,
with a maximum data throughput of 240 Mbytes/s. Link port
data is packed into 32- or 48-bit words, and can be directly read
by the core processor or DMA-transferred to on-chip memory.
Each link port has its own double-buffered input and output
registers. Clock/acknowledge handshaking controls link port
transfers. Transfers are programmable as either transmit or
receive.
Program Booting
The internal memory of the ADSP-2106x can be booted at
system power-up from either an 8-bit EPROM, a host processor, or through one of the link ports. Selection of the boot
source is controlled by the BMS (Boot Memory Select),
EBOOT (EPROM Boot), and LBOOT (Link/Host Boot) pins.
32-bit and 16-bit host processors can be used for booting.

DEVELOPMENT TOOLS
The ADSP-21060C is supported with a complete set of software
and hardware development tools, including an EZ-ICE InCircuit Emulator, EZ-Kit, and development software. The
SHARC EZ-Kit is a complete low cost package for DSP evaluation and prototyping. The EZ-Kit contains a PC plug-in card
(EZ-LAB®) with an ADSP-21062 (5 V) processor. The EZ-Kit
also includes an optimizing compiler, assembler, instruction
level simulator, run-time libraries, diagnostic utilities and a
complete set of example programs.
Analog Devices ADSP-21000 Family Development Software
includes an easy to use Assembler based on an algebraic syntax,
Assembly Library/Librarian, Linker, instruction-level Simulator,
an ANSI C optimizing Compiler, the CBug™ C Source—Level
Debugger and a C Runtime Library including DSP and mathematical functions. The ADSP-21000 Family Development
Software is available for both the PC and Sun platforms.
The ADSP-2106x EZ-ICE Emulator uses the IEEE 1149.1 JTAG
test access port of the ADSP-2106x processor to monitor and
control the target board processor during emulation. The EZ-ICE
provides full-speed 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 target system
loading or timing.
Further details and ordering information are available in the
ADSP-21000 Family Hardware and Software Development Tools
data sheet (ADDS-210xx-TOOLS). This data sheet can be
requested from any Analog Devices sales office or distributor.
In addition to the software and hardware development tools
available from Analog Devices, third parties provide a wide
range of tools supporting the SHARC processor family. Hardware tools include SHARC PC plug-in cards multiprocessor
SHARC VME boards, and daughter and modules with multiple
SHARCs and additional memory. These modules are based on
the SHARCPAC™ module specification. Third Party software
tools include an Ada compiler, DSP libraries, operating systems
and block diagram design tools.

DRx, TCLKx, RCLKx, LxDAT3-0, LxCLK, LxACK, TMS and
TDI)—these pins can be left floating. These pins have a logiclevel hold circuit that prevents the input from floating
internally.
PIN FUNCTION DESCRIPTIONS
ADSP-21060C pin definitions are listed below. All pins are
identical on the ADSP-21060C and ADSP-21060LC. Inputs
identified as synchronous (S) must meet timing requirements
with respect to CLKIN (or with respect to TCK for TMS,
TDI). Inputs identified as asynchronous (A) can be asserted
asynchronously to CLKIN (or to TCK for TRST).
A = Asynchronous
G = Ground
I = Input
O = Output
P = Power Supply
S = Synchronous
(A/D) = Active Drive (O/D) = Open Drain
T = Three-State (when SBTS is asserted, or when the
ADSP-2106x is a bus slave)
Unused inputs should be tied or pulled to VDD or GND,
except for ADDR31-0, DATA47-0, FLAG3-0, SW, and inputs that
have internal pull-up or pull-down resistors (CPA, ACK, DTx,
Pin
Type
Function
ADDR31-0
I/O/T
External Bus Address. The ADSP-2106x outputs addresses for external memory and peripherals on
these pins. In a multiprocessor system the bus master outputs addresses for read/writes of the internal
memory or IOP registers of other ADSP-2106xs. The ADSP-2106x inputs addresses when a host
processor or multiprocessing bus master is reading or writing its internal memory or IOP registers.
DATA47-0
I/O/T
External Bus Data. The ADSP-2106x inputs and outputs data and instructions on these pins. 32-bit
single-precision floating-point data and 32-bit fixed-point data is transferred over bits 47–16 of the
bus. 40-bit extended-precision floating-point data is transferred over bits 47–8 of the bus. 16-bit short
word data is transferred over bits 31–16 of the bus. In PROM boot mode, 8-bit data is transferred over
bits 23–16. Pull-up resistors on unused DATA pins are not necessary.
MS3-0
O/T
Memory Select Lines. These lines are asserted (low) as chip selects for the corresponding banks of
external memory. Memory bank size must be defined in the ADSP-2106x’s system control register
(SYSCON). The MS3-0 lines are decoded memory address lines that change at the same time as the
other address lines. When no external memory access is occurring the MS3-0 lines are inactive; they are
active however when a conditional memory access instruction is executed, whether or not the condition
is true. MS0 can be used with the PAGE signal to implement a bank of DRAM memory (Bank 0). In a
multiprocessing system the MS3-0 lines are output by the bus master.
RD
I/O/T
Memory Read Strobe. This pin is asserted (low) when the ADSP-2106x reads from external memory
devices or from the internal memory of other ADSP-2106xs. External devices (including other ADSP2106xs) must assert RD to read from the ADSP-2106x’s internal memory. In a multiprocessing system
RD is output by the bus master and is input by all other ADSP-2106xs.
WR
I/O/T
Memory Write Strobe. This pin is asserted (low) when the ADSP-2106x writes to external memory
devices or to the internal memory of other ADSP-2106xs. External devices must assert WR to write to
the ADSP-2106x’s internal memory. In a multiprocessing system WR is output by the bus master and
is input by all other ADSP-2106xs.
PAGE
O/T
DRAM Page Boundary. The ADSP-2106x asserts this pin to signal that an external DRAM page
boundary has been crossed. DRAM page size must be defined in the ADSP-2106x’s memory control
register (WAIT). DRAM can only be implemented in external memory Bank 0; the PAGE signal can
only be activated for Bank 0 accesses. In a multiprocessing system PAGE is output by the bus master.
ADRCLK
O/T
Clock Output Reference. In a multiprocessing system ADRCLK is output by the bus master.
SW
I/O/T
Synchronous Write Select. This signal is used to interface the ADSP-2106x to synchronous
memory devices (including other ADSP-2106xs). The ADSP-2106x asserts SW (low) to provide an
early indication of an impending write cycle, which can be aborted if WR is not later asserted (e.g., in a
conditional write instruction). In a multiprocessing system, SW is output by the bus master and is
input by all other ADSP-2106xs to determine if the multiprocessor memory access is a read or write.
SW is asserted at the same time as the address output. A host processor using synchronous writes must
assert this pin when writing to the ADSP-2106x(s).
ACK
I/O/S
Memory Acknowledge. External devices can deassert ACK (low) to add wait states to an external
memory access. ACK is used by I/O devices, memory controllers, or other peripherals to hold off
completion of an external memory access. The ADSP-2106x deasserts ACK as an output to add wait
states to a synchronous access of its internal memory. In a multiprocessing system, a slave ADSP2106x deasserts the bus master’s ACK input to add wait state(s) to an access of its internal memory.
The bus master has a keeper latch on its ACK pin that maintains the input at the level to which it was
last driven.

Type
Function
SBTS
I/S
Suspend Bus Three-State. External devices can assert SBTS (low) to place the external bus address,
data, selects and strobes in a high impedance state for the following cycle. If the ADSP-2106x
attempts to access external memory while SBTS is asserted, the processor will halt and the memory
access will not be completed until SBTS is deasserted. SBTS should only be used to recover from host
processor/ADSP-2106x deadlock, or used with a DRAM controller.
IRQ2-0
I/A
Interrupt Request Lines. May be either edge-triggered or level-sensitive.
FLAG3-0
I/O/A
Flag Pins. Each is configured via control bits as either an input or output. As an input, it can be
tested as a condition. As an output, it can be used to signal external peripherals.
TIMEXP
O
Timer Expired. Asserted for four cycles when the timer is enabled and TCOUNT decrements to
zero.
HBR
I/A
Host Bus Request. Must be asserted by a host processor to request control of the ADSP-2106x’s
external bus. When HBR is asserted in a multiprocessing system, the ADSP-2106x that is bus master
will relinquish the bus and assert HBG. To relinquish the bus, the ADSP-2106x places the address,
data, select and strobe lines in a high impedance state. HBR has priority over all ADSP-2106x bus
requests (BR6-1) in a multiprocessing system.
HBG
I/O
Host Bus Grant. Acknowledges an HBR bus request, indicating that the host processor may take
control of the external bus. HBG is asserted (held low) by the ADSP-2106x until HBR is released. In a
multiprocessing system, HBG is output by the ADSP-2106x bus master and is monitored by all others.
CS
I/A
Chip Select. Asserted by host processor to select the ADSP-2106x.
REDY (O/D) O
Host Bus Acknowledge. The ADSP-2106x deasserts REDY (low) to add wait states to an asynchronous access of its internal memory or IOP registers by a host. Open drain output (O/D) by default; can
be programmed in ADREDY bit of SYSCON register to be active drive (A/D). REDY will only be
output if the CS and HBR inputs are asserted.

BR6-1
I/O/S
Multiprocessing Bus Requests. Used by multiprocessing ADSP-2106xs to arbitrate for bus mastership. An ADSP-2106x only drives its own BRx line (corresponding to the value of its ID2-0 inputs) and
monitors all others. In a multiprocessor system with less than six ADSP-2106xs, the unused BRx pins
should be pulled high; the processor’s own BRx line must not be pulled high or low because it is an
output.
ID2-0
I
Multiprocessing ID. Determines which multiprocessing bus request (BR1 – BR6) is used by ADSP2106x. ID = 001 corresponds to BR1, ID = 010 corresponds to BR2, etc. ID = 000 in single-processor
systems. These lines are a system configuration selection which should be hardwired or only changed
at reset.
RPBA
I/S
Rotating Priority Bus Arbitration Select. When RPBA is high, rotating priority for multiprocessor
bus arbitration is selected. When RPBA is low, fixed priority is selected. This signal is a system configuration selection which must be set to the same value on every ADSP-2106x. If the value of RPBA is
changed during system operation, it must be changed in the same CLKIN cycle on every ADSP-2106x.
CPA (O/D)
I/O
Core Priority Access. Asserting its CPA pin allows the core processor of an ADSP-2106x bus slave
to interrupt background DMA transfers and gain access to the external bus. CPA is an open drain
output that is connected to all ADSP-2106xs in the system. The CPA pin has an internal 5 kΩ pull-up
resistor. If core access priority is not required in a system, the CPA pin should be left unconnected.

Link Port Acknowledge (Link Ports 0–5). Each LxACK pin has a 50 kΩ internal pull-down resistor
that is enabled or disabled by the LPDRD bit of the LCOM register.
EBOOT
I
EPROM Boot Select. When EBOOT is high, the ADSP-2106x is configured for booting from an 8bit EPROM. When EBOOT is low, the LBOOT and BMS inputs determine booting mode. See table
below. This signal is a system configuration selection that should be hardwired.
LBOOT
I
Link Boot. When LBOOT is high, the ADSP-2106x is configured for link port booting. When
LBOOT is low, the ADSP-2106x is configured for host processor booting or no booting. See table
below. This signal is a system configuration selection that should be hardwired.
BMS
I/O/T*
Boot Memory Select. Output: Used as chip select for boot EPROM devices (when EBOOT = 1,
LBOOT = 0). In a multiprocessor system, BMS is output by the bus master. Input: When low, indicates that no booting will occur and that ADSP-2106x will begin executing instructions from external

TARGET BOARD CONNECTOR FOR EZ-ICE PROBE
The 14-pin, 2-row pin strip header is keyed at the Pin 3 location —
Pin 3 must be removed from the header. The pins must be
0.025 inch square and at least 0.20 inch in length. Pin spacing
should be 0.1 × 0.1 inches. Pin strip headers are available from
vendors such as 3M, McKenzie and Samtec.
The ADSP-2106x EZ-ICE Emulator uses the IEEE 1149.1
JTAG test access port of the ADSP-2106x to monitor and control
the target board processor during emulation. The EZ-ICE probe
requires the ADSP-2106x’s CLKIN, TMS, TCK, TRST, TDI,
TDO, EMU, and GND signals be made accessible on the target
system via a 14-pin connector (a 2 row × 7 pin strip header) such
as that shown in Figure 5. The EZ-ICE probe plugs directly onto
this connector for chip-on-board emulation. You must add this
connector to your target board design if you intend to use the
ADSP-2106x EZ-ICE. The total trace length between the EZICE connector and the furthest device sharing the EZ-ICE
JTAG pins should be limited to 15 inches maximum for guaranteed operation. This length restriction must include EZ-ICE
JTAG signals that are routed to one or more ADSP-2106x
devices, or a combination of ADSP-2106x devices and other
JTAG devices on the chain.
The BTMS, BTCK, BTRST and BTDI signals are provided so
the test access port can also be used for board-level testing.
When the connector is not being used for emulation, place
jumpers between the Bxxx pins and the xxx pins. If the test
access port will not be used for board testing, tie BTRST to GND
and tie or pull BTCK up to VDD. The TRST pin must be
asserted after power-up (through BTRST on the connector) or
held low for proper operation of the ADSP-2106x. None of the
Bxxx pins (Pins 5, 7, 9, 11) are connected on the EZ-ICE probe.
The JTAG signals are terminated on the EZ-ICE probe as
follows:

ADSP-21060C/ADSP-21060LC
CLKIN and EMU should be treated as critical signals in terms
of skew, and should be laid out as short as possible on your
board. If TCK, TMS and CLKIN are driving a large number of
ADSP-21060 (more than eight) in your system, then treat them
as a clock tree using multiple drivers to minimize skew. (See
Figure 7, JTAG Clock Tree, and Clock Distribution in the
High Frequency Design Considerations section of the ADSP2106x User’s Manual, Second Edition.)
Connecting CLKIN to Pin 4 of the EZ-ICE header is optional.
The emulator only uses CLKIN when directed to perform operations such as starting, stopping and single-stepping multiple
ADSP-21060 in a synchronous manner. If you do not need these
operations to occur synchronously on the multiple processors,
simply tie Pin 4 of the EZ-ICE header to ground.
If synchronous multiprocessor operations are needed and CLKIN
is connected, clock skew between the multiple ADSP-21060C/
ADSP-21060LC processors and the CLKIN pin on the EZ-ICE
header must be minimal. If the skew is too large, synchronous
operations may be off by one or more cycles between processors. For synchronous multiprocessor operation TCK, TMS,
If synchronous multiprocessor operations are not needed (i.e.,
CLKIN is not connected), just use appropriate parallel termination on TCK and TMS. TDI, TDO, EMU, and TRST are not
critical signals in terms of skew.

ESD SENSITIVITY
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-21060C/ADSP-21060LC 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.
WARNING!
ESD SENSITIVE DEVICE
TIMING SPECIFICATIONS
See Figure 28 under Test Conditions for voltage reference
levels.
Two speed grades of the ADSP-21060C are offered, 40 MHz
and 33.3 MHz. The specifications shown are based on a
CLKIN frequency of 40 MHz (tCK = 25 ns). The DT derating
allows specifications at other CLKIN frequencies (within the
min–max range of the tCK specification; see Clock Input below).
DT is the difference between the actual CLKIN period and a
CLKIN period of 25 ns:
Switching Characteristics specify how the processor changes its
signals. You have no control over this timing—circuitry external
to the processor must be designed for compatibility with these
signal characteristics. Switching characteristics tell you what the
processor will do in a given circumstance. You can also use
switching characteristics to ensure that any timing requirement
of a device connected to the processor (such as memory) is
satisfied.
DT = tCK – 25 ns
Use the exact timing information given. Do not attempt to
derive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results for
an individual device, the values given in this data sheet reflect
statistical variations and worst cases. Consequently, you cannot
meaningfully add parameters to derive longer times.
REV. B
Timing Requirements apply to signals that are controlled by circuitry external to the processor, such as the data input for a
read operation. Timing requirements guarantee that the processor operates correctly with other devices.

Applies after the power-up sequence is complete. At power-up, the processor’s internal phase-locked loop requires no more than 2000 CLKIN cycles while RESET
is low, assuming stable V DD and CLKIN (not including start-up time of external clock oscillator).

Only required if multiple ADSP-2106xs must come out of reset synchronous to CLKIN with program counters (PC) equal (i.e., for a SIMD system). Not required
for multiple ADSP-2106xs communicating over the shared bus (through the external port), because the bus arbitration logic synchronizes itself automatically after reset.

For first asynchronous access after HBR and CS asserted, ADDR31-0 must be a non-MMS value 1/2 t CK before RD or WR goes low or by t HBGRCSV after HBG goes
low. This is easily accomplished by driving an upper address signal high when HBG is asserted. See the “Host Processor Control of the ADSP-2106x” section in the
ADSP-2106x SHARC User’s Manual, Second Edition.

tSDATDGL is the data setup requirement if DMARx is not being used to hold off completion of a write. Otherwise, if DMARx low holds off completion of the write, the
data can be driven tDATDRH after DMARx is brought high.
3
tVDATDGH is valid if DMARx is not being used to hold off completion of a read. If DMARx is used to prolong the read, then t VDATDGH = 8 + 9DT/16 + (n × tCK) where
n equals the number of extra cycles that the access is prolonged.

Link Ports: 2 CLK Speed Operation
Calculation of link receiver data setup and hold relative to link clock is required to determine the maximum allowable skew that can
be introduced in the transmission path between LDATA and LCLK. Setup skew is the maximum delay that can be introduced in
LDATA relative to LCLK, (setup skew = tLCLKTWH min – tDLDCH – tSLDCL). Hold skew is the maximum delay that can be introduced in LCLK relative to LDATA, (hold skew = tLCLKTWL min – tHLDCH – tHLDCL). Calculations made directly from 2 × speed

OUTPUT DRIVE CURRENTS
Figure 28 shows typical I-V characteristics for the output drivers
of the ADSP-2106x. The curves represent the current drive
capability of the output drivers as a function of output voltage.
POWER DISSIPATION
Total power dissipation has two components, one due to internal circuitry and one due to the switching of external output
drivers. Internal power dissipation is dependent on the instruction execution sequence and the data operands involved. Internal power dissipation is calculated in the following way:
PINT = IDDIN × VDD
The external component of total power dissipation is caused by
the switching of output pins. Its magnitude depends on:
– the number of output pins that switch during each cycle (O)
– the maximum frequency at which they can switch (f)
– their load capacitance (C)
– their voltage swing (VDD)
and is calculated by:

The load capacitance should include the processor’s package
capacitance (CIN). The switching frequency includes driving the
load high and then back low. Address and data pins can drive
high and low at a maximum rate of 1/(2tCK). The write strobe
can switch every cycle at a frequency of 1/tCK. Select pins switch
at 1/(2tCK), but selects can switch on each cycle.
–A system with one bank of external data memory RAM (32-bit)
–Four 128K × 8 RAM chips are used, each with a load of 10 pF
–External data memory writes occur every other cycle, a rate
of 1/(4tCK), with 50% of the pins switching
–The instruction cycle rate is 40 MHz (tCK = 25 ns).
The PEXT equation is calculated for each class of pins that can
drive:

PTOTAL = PEXT + (IDDIN2 × 5.0 V )
Note that the conditions causing a worst-case PEXT are different
from those causing a worst-case PINT. Maximum PINT cannot
occur while 100% of the output pins are switching from all ones
to all zeros. Note also that it is not common for an application to
have 100% or even 50% of the outputs switching simultaneously.
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 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 following equation:

The output disable time tDIS is the difference between tMEASURED
and tDECAY as shown in Figure 25. The time tMEASURED 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. tDECAY is calculated with test loads CL and
IL, and with ∆V equal to 0.5 V.
Output Enable Time
Output pins are considered to be enabled when they have made
a transition from a high impedance state to when they start
driving. The output enable time tENA is the interval from when a
reference signal reaches a high or low voltage level to when the
output has reached a specified high or low trip point, as shown
in the Output Enable/Disable diagram (Figure 25). If multiple
pins (such as the data bus) are enabled, the measurement value
is that of the first pin to start driving.

Example System Hold Time Calculation
IOL
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-2106x’s output voltage
and the input threshold for the device requiring the hold time. A
typical ∆V will be 0.4 V. 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 minimum
disable time (i.e., tDATRWH for the write cycle).

Capacitive Loading
Output delays and holds are based on standard capacitive loads:
50 pF on all pins (see Figure 26). The delay and hold specifications given should be derated by a factor of 1.5 ns/50 pF for
loads other than the nominal value of 50 pF. Figures 29–30,
33–34 show how output rise time varies with capacitance. Figures 31, 35 show graphically how output delays and holds vary
with load capacitance. (Note that this graph or derating does
not apply to output disable delays; see the previous section
Output Disable Time under Test Conditions.) The graphs of
Figures 29, 30 and 31 may not be linear outside the ranges
shown.

ENVIRONMENTAL CONDITIONS
Thermal Characteristics
The ADSP-2106x is packaged in a 240-lead thermally enhanced
ceramic QFP (CQFP). There are two package versions, one
with a copper/tungsten heat slug on top of the package (CZ) for
air cooling, and one with the heat slug on the bottom (CW) for
cooling through the board. The ADSP-2106x is specified for a
case temperature (TCASE). To ensure that the TCASE data sheet
specification is not exceeded, a heatsink and/or an air flow
source may be used. A heatsink should be attached with a thermal adhesive.
TCASE = TAMB + (PD × θCA )
TCASE = Case temperature (measured on the heat slug surface)
