ADSP-21061/ADSP-21061L
Porting Code from ADSP-21060 or ADSP-21062 to the
ADSP-21061
The ADSP-21061 is pin compatible with the ADSP-21060/
ADSP-21061/ADSP-21062 processors. The ADSP-21061 pins
that correspond to the Link Port pins of the ADSP-21060/
ADSP-21062 are no-connects.
The ADSP-21061 is object code compatible with the ADSP-
21060/ADSP-21062 except for the following functional
changes:
The ADSP-21061 memory is organized into two blocks
with eight columns that are 4K deep per block. The
ADSP-21060/ADSP-21062 memory has 16 columns per block.
Link port functions are not available.
Handshake external port DMA pins
DMAR2
and
DMAG2
are assigned to external port DMA Channel 6 instead of
Channel 8.
2-D DMA capability of the SPORT is not available.
The modify registers in SPORT DMA are not programmable.
On the ADSP-21061, Block 0 starts at the beginning of internal
memory, normal word address 0x0002 0000. Block 1 starts at
the end of Block 0, with contiguous addresses. The remaining
addresses in internal memory are divided into blocks that alias
into Block 1. This allows any code or data stored in Block 1 on
the ADSP-21062 to retain the same addresses on the ADSP-
21061—these addresses will alias into the actual Block 1 of each
processor.
If you develop your application using the ADSP-21062, but will
migrate to the ADSP-21061, use only the first eight columns of
each memory bank. Limit your application to 8K of instructions
or up to 16K of data in each bank of the ADSP-21062, or any
combinations of instructions or data that does not exceed the
memory bank.
DEVELOPMENT TOOLS
The same EZ-ICE hardware can be used for the ADSP-21060/
ADSP-21062, to fully emulate the ADSP-21061, with the excep-
tion of displaying and modifying the two new SPORTS
registers. The emulator will not display these two registers,
but your code can use them.
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 EZ-ICE Emulator uses the IEEE 1149.1 JTAG test access
port of the ADSP-21061 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 inter-
face—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.
ADDITIONAL INFORMATION
The ADSP-21061 is supported with a complete set of software
and hardware development tools, including an EZ-ICE In-
Circuit Emulator, EZ-Kit Lite, and development software. The
SHARC EZ-Kit Lite (ADDS-2106x-EZ-Lite) is a complete low
cost package for DSP evaluation and prototyping. The EZ-Kit
Lite contains an evaluation board with an ADSP-21061 (5 V)
processor and provides a serial connection to your PC. The EZ-
Kit Lite also includes an optimizing compiler, assembler, in-
struction level simulator, run-time libraries, diagnostic utilities
and a complete set of example programs.
This data sheet provides a general overview of the ADSP-21061
architecture and functionality. For detailed information on the
ADSP-21000 Family core architecture and instruction set, refer to
