GENERAL DESCRIPTION
The ADSP-21060 SHARC—Super Harvard Architecture Com-
puter—is a signal processing microcomputer that offers new
capabilities and levels of performance. The ADSP-2106x
SHARCs are 32-bit processors optimized for high performance
DSP applications. The ADSP-2106x builds on the ADSP-
21000 DSP core to form a complete system-on-a-chip, adding a
dual-ported on-chip SRAM and integrated I/O peripherals sup-
ported by a dedicated I/O bus.
Fabricated in a high speed, low power CMOS process, the
ADSP-2106x has a 25 ns instruction cycle time and operates
at 40MIPS. With its on-chip instruction cache, the processor
can execute every instruction in a single cycle. Table I shows
performance benchmarks for the ADSP-2106x.
The ADSP-2106x SHARC represents a new standard of inte-
gration for signal computers, combining a high performance
floating-point DSP core with integrated, on-chip system features
including a 4 Mbit SRAM memory host processor interface,
DMA controller, serial ports, and link port and parallel bus
connectivity for glueless DSP multiprocessing.

ADSP-21000 FAMILY CORE ARCHITECTURE

The ADSP-2106x includes the following architectural features
of the ADSP-21000 family core. The ADSP-21060 is code- and
function-compatible with the ADSP-21061 and ADSP-21062.
Independent, Parallel Computation Units

The arithmetic/logic unit (ALU), multiplier and shifter all per-
form single-cycle instructions. The three units are arranged in
parallel, maximizing computational throughput. Single multi-
function instructions execute parallel ALU and multiplier opera-
tions. These computation units support IEEE 32-bit single-
precision floating-point, extended precision 40-bit floating-
point, and 32-bit fixed-point data formats.
Figure 2.ADSP-2106x System
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 pri-
mary, 16 secondary) register file, combined with the ADSP-
21000 Harvard architecture, allows unconstrained data flow
between computation units and internal memory.
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 pro-
gram 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 simulta-
neously fetch two operands and an instruction (from the cache),
all in a single cycle.
ADSP-21060/ADSP-21060L
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) imple-
ment 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 second-
ary). The DAGs automatically handle address pointer wrap-
around, 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.
ADSP-21060/ADSP-21060L FEATURES

Augmenting the ADSP-21000 family core, the ADSP-21060
adds the following architectural features:
Dual-Ported On-Chip Memory

The ADSP-21060 contains four megabits of on-chip SRAM,
organized as two blocks of 2 Mbits each, which can be config-
ured 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 con-
troller. 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-21060, the memory can be configured as a maxi-
mum of 128K words of 32-bit data, 256K words of 16-bit data,
80K words of 48-bit instructions (or 40-bit data), or combina-
tions of different word sizes up to four 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 that effec-
tively doubles the amount of data that may 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-
Off-Chip Memory and Peripherals Interface

The ADSP-2106x’s external port provides the processor’s inter-
face to off-chip memory and peripherals. The 4-gigaword off-
chip 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 sim-
plified 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 exter-
nal 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 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.
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 exter-
nal 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 inter-
rupt generation upon completion of DMA transfers and DMA
chaining for automatic linked DMA transfers.
Serial Ports
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 maxi-
mum 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.
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 multi-
processing 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. Maxi-
mum throughput for interprocessor data transfer is 240 Mbytes/s
over the link ports or external port. Broadcast writes allow simulta-
neous 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 addi-
tional 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 commu-
nication 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 proces-
sor, 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.

level simulator, run-time libraries, diagnostic utilities and a
complete set of example programs.
The same EZ-ICE hardware can be used for the ADSP-21061/
ADSP-21062, to fully emulate the ADSP-21060, with the excep-
tion of displaying and modifying the two new SPORTS registers
unique to ADSP-21061.
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 Optimizing Compiler includes
Numerical C extensions based on the work of the ANSI Nu-
merical C Extensions Group. Numerical C provides extensions
to the C language for array selections, vector math operations,
complex data types, circular pointers and variably dimensioned
arrays. The ADSP-21000 Family Development Software is
available for both the PC and Sun platforms.
The ADSP-21060 EZ-ICE Emulator uses the IEEE 1149.1
JTAG test access port of the ADSP-21060 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. Hard-
ware 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.

PIN FUNCTION DESCRIPTIONS

ADSP-21060 pin definitions are listed below. All pins are iden-
tical on the ADSP-21060 and ADSP-21060L. 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, SW, 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.

TARGET BOARD CONNECTOR FOR EZ-ICE PROBE
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 EZ-
ICE connector and the furthest device sharing the EZ-ICE
JTAG pins should be limited to 15 inches maximum for guaran-
teed 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.
Figure 5.Target Board Connector For ADSP-2106x EZ-ICE
Emulator (Jumpers in Place)
Figure 6.JTAG Scan Path Connections for Multiple ADSP-2106x Systems
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 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:
*TRST is driven low until the EZ-ICE probe is turned on by the emulator at
software start-up. After software start-up, TRST is driven high.
Figure 6 shows JTAG scan path connections for systems that
contain multiple ADSP-2106x processors.
ADSP-21060/ADSP-21060L
Figure 7.JTAG Clocktree for Multiple ADSP-2106x Systems
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 mul-
tiple ADSP-21061 in a synchronous manner. If you do not need
these operations to occur synchronously on the multiple proces-
sors, 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-
21061/ADSP-21061L processors and the CLKIN pin on the
EZ-ICE header must be minimal. If the skew is too large, syn-
chronous 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 num-
ber of ADSP-21061 (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
ADSP-2106x User’s Manual, Second Edition.)
If synchronous multiprocessor operations are not needed (i.e.,
CLKIN is not connected), just use appropriate parallel termina-
tion on TCK and TMS. TDI, TDO, EMU and TRST are not
critical signals in terms of skew.

2100 Family JTAG EZ-ICE User’s Guide and Reference.

TIMING SPECIFICATIONS

Two speed grades of the ADSP-21060 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:
DT = tCK – 25ns
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.
See Figure 28 under Test Conditions for voltage reference
levels.
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.
Timing Requirements apply to signals that are controlled by cir-
cuitry external to the processor, such as the data input for a
read operation. Timing requirements guarantee that the proces-
sor operates correctly with other devices.

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-2106x 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.

When accessing a slave ADSP-2106x, these switching character-
istics must meet the slave’s timing requirements for synchronous
read/writes (see Synchronous Read/Write—Bus Slave). The
slave ADSP-2106x must also meet these (bus master) timing
requirements for data and acknowledge setup and hold times.
