Figure 2. ADSP-2106x System Sample Configuration
SHARC FAMILY CORE ARCHITECTURE
The ADSP-2106x continues SHARC’s industry-leading standards of integration for DSPs, combining a high performance
32-bit DSP core with integrated, on-chip system features.
The ADSP-2106x includes the following architectural features
of the ADSP-21000 family core. The ADSP-2106x processors
are code- and function-compatible with the ADSP-21020.
The block diagram on Page 1 illustrates the following architectural features:
Independent, Parallel Computation Units
• Computation units (ALU, multiplier and shifter) with a
shared data register file
• Data address generators (DAG1, DAG2)
• Program sequencer with instruction cache
• PM and DM buses capable of supporting four 32-bit data
transfers between memory and the core at every core processor cycle
• Interval timer
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 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 ADSP-21000
Harvard architecture, allows unconstrained data flow between
computation units and internal memory.
• On-chip SRAM
• External port for interfacing to off-chip memory and
peripherals
• Host port and multiprocessor Interface
• DMA controller

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 on Page 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.
Instruction Cache
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.
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
ADSP-2106x can conditionally execute a multiply, an add, a
subtract and a branch, all in a single instruction.
MEMORY AND I/O INTERFACE FEATURES
The ADSP-2106x processors add the following architectural
features to the SHARC family core.
The ADSP-21062/ADSP-21062L contains two megabits of onchip SRAM, and the ADSP-21060/ADSP-21060L contains
4M bits of on-chip SRAM. The internal memory is organized as
two equal sized blocks of 1M bit each for the ADSP-21062/
ADSP-21062L and two equal sized blocks of 2M bits each for
the ADSP-21060/ADSP-21060L. Each 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.
On the ADSP-21062/ADSP-21062L, the memory can be configured as a maximum of 64k words of 32-bit data, 128k words of
16-bit data, 40k words of 48-bit instructions (or 40-bit data), or
combinations of different word sizes up to two megabits. All of
the memory can be accessed as 16-bit, 32-bit, or 48-bit words.
|
A 16-bit floating-point storage format is supported, which effectively doubles the amount of data that can be stored on-chip.
Conversion between the 32-bit floating-point and 16-bit floating-point formats is done in a single instruction.
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
ADSP-2106x’s external port.
On-Chip Memory and Peripherals Interface
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.
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
Dual-Ported On-Chip Memory
Rev. F
On the ADSP-21060/ADSP-21060L, 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.
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.

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.
DMA Controller
The ADSP-2106x’s on-chip DMA controller allows zero-overhead 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.
Multiprocessing
The ADSP-2106x offers powerful features tailored to multiprocessor DSP systems. The unified address space (see Figure 4)
allows direct interprocessor accesses of each ADSP-2106x’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
240M bytes/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.
DMA transfers can occur between the ADSP-2106x’s internal
memory and external memory, external peripherals, or a host
processor. DMA transfers can also occur between the ADSP2106x’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

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 of data per cycle. Linkport 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 240M bytes/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.
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)
• Insert breakpoints
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.
• Set conditional breakpoints on registers, memory, and
stacks
• Trace instruction execution
• Perform linear or statistical profiling of program execution
Program Booting
The internal memory of the ADSP-2106x can be booted at system power-up from 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. The processor also supports a no-boot mode in which instruction execution is sourced
from the external memory.
• Fill, dump, and graphically plot the contents of memory
• Perform source level debugging
• Create custom debugger windows
The VisualDSP++ IDDE lets programmers define and manage
DSP software development. Its dialog boxes and property pages
let programmers configure and manage all of the ADSP-2106x
development tools, including the color syntax highlighting in
the VisualDSP++ editor. This capability permits:
DEVELOPMENT TOOLS
The ADSP-2106x is supported by a complete set of
CROSSCORE®† software development tools, including Analog
Devices emulators and VisualDSP++®‡ development environment. The same emulator hardware that supports other SHARC
processors also fully emulates the ADSP-2106x.
The VisualDSP++ project management environment lets programmers develop and debug an application. This environment
includes an easy to use assembler (which 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 DSP assembly. The ADSP-2106x
SHARC DSP 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
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
†
‡
• Control in how the development tools process inputs and
generate outputs
• Maintenance of a one-to-one correspondence with the
tools’ command line switches
The VisualDSP++ kernel (VDK) incorporates scheduling and
resource management tailored specifically to address the memory and timing constraints of DSP 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, preemptive, 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 via 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.

ADDITIONAL INFORMATION
EVALUATION KIT
This data sheet provides a general overview of the ADSP-2106x
architecture and functionality. For detailed information on the
ADSP-21000 family core architecture and instruction set, refer
to the ADSP-2106x SHARC User’s Manual, Revision 2.1.
Analog Devices offers a range of EZ-KIT Lite®† evaluation platforms to use as a cost-effective method to learn more about
developing or prototyping applications with Analog Devices
processors, platforms, and software tools. Each EZ-KIT Lite
includes an evaluation board along with an evaluation suite of
the VisualDSP++ development and debugging environment
with the C/C++ compiler, assembler, and linker. Also included
are sample application programs, power supply, and a USB
cable. All evaluation versions of the software tools are limited
for use only with the EZ-KIT Lite product.
The USB controller on the EZ-KIT Lite board connects the
board to the USB port of the user’s PC, enabling the
VisualDSP++ evaluation suite to emulate the on-board processor in-circuit. This permits the customer to download, execute,
and debug programs for the EZ-KIT Lite system. It also allows
in-circuit programming of the on-board flash device to store
user-specific boot code, enabling the board to run as a standalone unit, without being connected to the PC.
With a full version of VisualDSP++ installed (sold separately),
engineers can develop software for the EZ-KIT Lite or any custom-defined system. Connecting an Analog Devices JTAG
emulator to the EZ-KIT Lite board enables high speed, nonintrusive emulation.
DESIGNING AN EMULATOR-COMPATIBLE DSP
BOARD (TARGET)
The Analog Devices family of emulators are tools that every
DSP developer needs to test and debug hardware and software
systems. Analog Devices has supplied an IEEE 1149.1 JTAG test
access port (TAP) on each JTAG DSP. 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. The emulator uses the TAP to access the internal features of
the DSP, allowing the developer to load code, set breakpoints,
observe variables, observe memory, and examine registers. The
DSP must be halted to send data and commands, but once an
operation has been completed by the emulator, the DSP system
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 DSP’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 the EE-68: Analog Devices JTAG Emulation Technical

PIN FUNCTION DESCRIPTIONS
The ADSP-2106x pin definitions are listed below. 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).
Unused inputs should be tied or pulled to VDD or GND, except
for ADDR31–0, DATA47–0, FLAG3–0, and inputs that have
internal pull-up or pull-down resistors (CPA, ACK, DTx, DRx,
TCLKx, RCLKx, LxDAT3–0, LxCLK, LxACK, TMS, and
TDI)—these pins can be left floating. These pins have a
logic-level hold circuit that prevents the input from floating
internally.
Table 3. Pin Descriptions
Pin
ADDR31–0
Type
I/O/T
Function
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/write 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 singleprecision 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.
O/T
Memory Select Lines. These lines are asserted (low) as chip selects for the corresponding banks of external
MS3–0
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 ADSP-2106xs) 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.
I/O/T
Memory Write Strobe. This pin is asserted (low) when the ADSP-2106x writes to external memory devices
WR
or to the internal memory of other ADSP-2106xs. External devices must assert WR to write to the ADSP2106x’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).
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)

Table 3. Pin Descriptions (Continued)
Pin
ACK
Type
I/O/S
Function
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 waitstates to a synchronous
access of its internal memory. In a multiprocessing system, a slave ADSP-2106x 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.
I/S
Suspend Bus Three-State. External devices can assert SBTS (low) to place the external bus address, data,
SBTS
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, they can be tested as
a condition. As an output, they 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. This pin 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 a 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 (O/D)
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. This pin is an open-drain output (O/D) by default; it can be
programmed in the ADREDY bit of the SYSCON register to be active drive (A/D). REDY will only be output if
the CS and HBR inputs are asserted.
DMAR2–1
I/A
DMA Request 1 (DMA Channel 7) and DMA Request 2 (DMA Channel 8).
DMAG2–1
O/T
DMA Grant 1 (DMA Channel 7) and DMA Grant 2 (DMA Channel 8).
BR6–1
I/O/S
Multiprocessing Bus Requests. Used by multiprocessing ADSP-2106xs to arbitrate for bus master-ship. 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
O (O/D)
Multiprocessing ID. Determines which multiprocessing bus request (BR1– BR6) is used by ADSP-2106x.
ID = 001 corresponds to BR1, ID = 010 corresponds to BR2, etc. ID = 000 in single-processor systems. These
lines are a system configuration selection that should be hardwired or changed at reset only.
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 that 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
I/O (O/D)
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 k: pull-up resistor. If core access priority is
not required in a system, the CPA pin should be left unconnected.
DTx
O
Data Transmit (Serial Ports 0, 1). Each DT pin has a 50 k: internal pull-up resistor.
DRx
I
Data Receive (Serial Ports 0, 1). Each DR pin has a 50 k: internal pull-up resistor.
TCLKx
I/O
Transmit Clock (Serial Ports 0, 1). Each TCLK pin has a 50 k: internal pull-up resistor.
RCLKx
I/O
Receive Clock (Serial Ports 0, 1). Each RCLK pin has a 50 k: internal pull-up resistor.
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)

LxACK
I/O
Link Port Acknowledge (Link Ports 0–5). Each LxACK pin has a 50 k: 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 8-bit EPROM.
When EBOOT is low, the LBOOT and BMS inputs determine booting mode. See the table in the BMS pin
description 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 the table in the BMS pin
description below. This signal is a system configuration selection that should be hardwired.
I/OT
Boot Memory Select. Output: Used as chip select for boot EPROM devices (when EBOOT = 1, LBOOT = 0).
BMS
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 memory. See table below. This
input is a system configuration selection that should be hardwired. *Three-statable only in EPROM boot

TARGET BOARD CONNECTOR FOR EZ-ICE PROBE
The ADSP-2106x EZ-ICE® Emulator uses the IEEE
1149.1JTAG 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 EZ-ICE connector and the furthest device sharing
the EZ-ICE JTAG pin 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 JTAG signals are terminated on the EZ-ICE probe as shown
in Table 4.

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 u 0.1 inches. Pin strip headers are available from
vendors such as 3M, McKenzie, and Samtec. The BTMS, BTCK,
BTRST, and BTDI signals are provided so that 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 as shown in
Figure 5. If you are not going to use the test access port for
board testing, tie BTRST to GND and tie or pull up BTCK to
VDD. The TRST pin must be asserted (pulsed low) after powerup (through BTRST on the connector) or held low for proper
operation of the ADSP-2106x. None of the Bxxx pins (Pins 5, 7,
9, and 11) are connected on the EZ-ICE probe.

If synchronous multiprocessor operations are needed and
CLKIN is connected, clock skew between the multiple
ADSP-2106x 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,
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-2106xs (more than eight) in your system, then treat them
as a “clock tree” using multiple drivers to minimize skew. (See
Figure 7 and “JTAG Clock Tree” and “Clock Distribution” in
the “High Frequency Design Considerations” section of the
ADSP-2106x User’s Manual, Revision 2.1.)
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.

ADSP-21000 Family JTAG EZ-ICE User's Guide and Reference.

EXTERNAL POWER DISSIPATION (5 V)
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:
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.
Example: Estimate PEXT with the following assumptions:
• A system with one bank of external data memory RAM
(32-bit)
PINT = IDDIN u VDD
• Four 128K u 8 RAM chips are used, each with a load of
10 pF
The external component of total power dissipation is caused by
the switching of output pins. Its magnitude depends on:
• External data memory writes occur every other cycle, a rate
of 1/(4tCK), with 50% of the pins switching
• the number of output pins that switch during each cycle
(O)
• The instruction cycle rate is 40 MHz (tCK = 25 ns)
• the maximum frequency at which they can switch (f)
The PEXT equation is calculated for each class of pins that can
drive:
• their load capacitance (C)
A typical power consumption can now be calculated for these
conditions by adding a typical internal power dissipation:
• their voltage swing (VDD)
and is calculated by:
PTOTAL = PEXT + (IDDIN2 u 5.0 V)
PEXT = O u C u VDD2 u f
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
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.

TIMING SPECIFICATIONS
ESD (electrostatic discharge) sensitive device.
Charged devices and circuit boards can discharge
without detection. Although this product features
patented or proprietary protection circuitry, damage
may occur on devices subjected to high energy ESD.
Therefore, proper ESD precautions should be taken to
avoid performance degradation or loss of functionality.
The ADSP-2106x processors are available at maximum processor speeds of 33 MHz (–133), and 40 MHz (–160). The timing
specifications are based on a CLKIN frequency of 40 MHz
tCK = 25 ns). The DT derating factor enables the calculation for
timing specifications within the min to max range of the tCK
specification (see Table 9). DT is the difference between the derated CLKIN period and a CLKIN period of 25 ns:
DT = tCK – 25 ns

Synchronous Read/Write—Bus Master
Use these specifications for interfacing to external memory systems that require CLKIN—relative timing or for accessing a
slave ADSP-2106x (in multiprocessor memory space). These
synchronous switching characteristics are also valid during
asynchronous memory reads and writes except where noted (see
Memory Read—Bus Master on Page 25 and Memory Write—
Bus Master on Page 26). When accessing a slave ADSP-2106x,
these switching characteristics must meet the slave’s timing
requirements for synchronous read/writes (see Synchronous
Read/Write—Bus Slave on Page 29). The slave ADSP-2106x
must also meet these (bus master) timing requirements for data
and acknowledge setup and hold times.

greater than 19 + 3DT/4, then ACK is valid 14 + DT/4 (max) after CLKIN. A slave that sees an address with an M field match will respond with ACK regardless of the state
of MMSWS or strobes. A slave will three-state ACK every cycle with tACKTR.

For first asynchronous access after HBR and CS asserted, ADDR31-0 must be a non-MMS value 1/2 tCK before RD or WR goes low or by tHBGRCSV 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

Asynchronous Read/Write—Host to ADSP-2106x
Use these specifications for asynchronous host processor
accesses of an ADSP-2106x, after the host has asserted CS and
HBR (low). After HBG is returned by the ADSP-2106x, the host
can drive the RD and WR pins to access the ADSP-2106x’s
internal memory or IOP registers. HBR and HBG are assumed
low for this timing. Not required if and address are valid tHBGRCSV
after goes low. For first access after asserted, ADDR31–0 must
be a non-MMS value 1/2 tCLK before or goes low or by tHBGRCSV
after goes low. This is easily accomplished by driving an upper
address signal high when is asserted. See the “Host Processor
Control of the ADSP-2106x” section in the ADSP-2106x

DMA Handshake
These specifications describe the three DMA handshake modes.
In all three modes, DMARx is used to initiate transfers. For
Handshake mode, DMAGx controls the latching or enabling of
data externally. For External handshake mode, the data transfer
is controlled by the ADDR31–0, RD, WR, PAGE, MS3–0, ACK,
and DMAGx signals. For Paced Master mode, the data transfer
is controlled by ADDR31–0, RD, WR, MS3–0, and ACK (not
DMAG). For Paced Master mode, the Memory Read-Bus Master, Memory Write-Bus Master, and Synchronous Read/WriteBus Master timing specifications for ADDR31–0, RD, WR,
MS3–0, PAGE, DATA63–0, and ACK also apply.

Only required for recognition in the current cycle.
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 tVDATDGH = tCK – 0.25tCCLK – 8 + (n × tCK) where n equals
the number of extra cycles that the access is prolonged.

Link Ports —2 × CLK Speed Operation
Hold skew is the maximum delay that can be introduced in
LCLK relative to LDATA:
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:
Hold Skew = tLCLKTWL min – tHLDCH – tHLDCL
Calculations made directly from 2 speed specifications will
result in unrealistically small skew times because they include
multiple tester guardbands.
Setup Skew = tLCLKTWH min – tDLDCH – tSLDCL
Note that link port transfers at 2× CLK speed at 40 MHz
(tCK = 25 ns) may fail. However, 2× CLK speed link port transfers at 33 MHz (tCK = 30 ns) work as specified.

TEST CONDITIONS
For the ac signal specifications (timing parameters), see Timing
Specifications on Page 21. These specifications include output
disable time, output enable time, and capacitive loading. The
timing specifications for the DSP apply for the voltage reference
levels in Figure 28.

Output Disable Time
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:
C L 'VP EXT = ------------IL
output has reached a specified high or low trip point, as shown
in the Output Enable/Disable diagram (Figure 29). 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
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 30). 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. Figure 32,
Figure 33, Figure 37, and Figure 38 show how output rise time
varies with capacitance. Figure 34 and Figure 36 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 Figure 32, Figure 33,
Figure 37, and Figure 38 may not be linear outside the ranges
shown.
The output disable time tDIS is the difference between
tMEASURED and tDECAY as shown in Figure 29. 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.

ENVIRONMENTAL CONDITIONS
Thermal Characteristics for CQFP Package
The ADSP-2106x processors are rated for performance under
TCASE environmental conditions specified in the Operating Conditions (5 V) on Page 15 and Operating Conditions (3.3 V) on
Page 18.
The ADSP-21060C/ADSP-21060LC are available in 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.
Thermal Characteristics for MQFP_PQ4 and PBGA
Packages
The ADSP-21060/ADSP-21060L and ADSP-21062/ADSP21062L are available in 240-lead thermally enhanced
MQFP_PQ4 and 225-ball plastic ball grid array packages. The
top surface of the thermally enhanced MQFP_PQ4 contains a
metal slug from which most of the die heat is dissipated. The
slug is flush with the top surface of the package. Note that the
metal slug is internally connected to GND through the device
substrate.
Both packages are specified for a case temperature (TCASE). To
ensure that the TCASE is not exceeded, a heatsink and/or an airflow source may be used. A heatsink should be attached with a
thermal adhesive.
