ADSP-21261  
EVALUATION KIT  
ADDITIONAL INFORMATION  
Analog Devices offers a range of EZ-KIT Lite®evaluation plat-  
forms 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.  
This data sheet provides a general overview of the ADSP-21261  
architecture and functionality. For detailed information on the  
ADSP-2126x family core architecture and instruction set, refer  
to the ADSP-2126x DSP Core Manual and the ADSP-21160  
SHARC DSP Instruction Set Reference.  
The USB controller on the EZ-KIT Lite board connects the  
board to the USB port of the user’s PC, enabling the Visu-  
alDSP++ 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 cus-  
tom-defined system. Connecting an Analog Devices JTAG  
emulator to the EZ-KIT Lite board enables high speed, nonin-  
trusive 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 inter-  
face—the emulator does not affect target system loading or  
timing. The emulator uses the TAP to access the internal fea-  
tures 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 sys-  
tem 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  
Reference on the Analog Devices website (www.analog.com)—  
use site search on “EE-68.” This document is updated regularly  
to keep pace with improvements to emulator support.
