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, pre-
emptive, 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 gen-
eration of various VDK-based objects, and visualizing the
system state, when debugging an application that uses the VDK.
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 DSP or external memory with a drag of
the mouse, and examine run-time stack and heap usage. The
expert linker is fully compatible with existing linker definition
file (LDF), allowing the developer to move between the graphi-
cal and textual environments.
In addition to the software development tools available from
Analog Devices, third parties provide a wide range of tools sup-
porting the SHARC processor family. Third-party software
tools include DSP libraries, real-time operating systems, and
block diagram design tools.
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
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, 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.
