Analog Devices, Inc.
Datasheet
Use the Expert Linker to visually manipulate the placement of
code and data on the embedded system. View memory utiliza-
tion in a color-coded graphical form, easily move code and data
to different areas of the processor or external memory with a
drag of the mouse and examine runtime stack and heap usage.
The expert linker is fully compatible with the existing linker def-
inition file (LDF), allowing the developer to move between the
graphical and textual environments.
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 processor PC plug-in cards. Third-
party software tools include DSP libraries, real-time operating
systems, and block diagram design tools.
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 processor, allowing the developer to load code, set
breakpoints, observe variables, observe memory, and examine
registers. The processor must be halted to send data and com-
mands, 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, signal buffering, signal ter-
mination, 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.
Evaluation Kit
Analog Devices offers a range of EZ-KIT Lite
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.
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 proces-
sor 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 stand-
alone 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 one of Analog Devices
JTAG emulators to the EZ-KIT Lite board enables high speed,
non-intrusive emulation.
ADDITIONAL INFORMATION
This data sheet provides a general overview of the
