Getting Started With SHARC Processors 2-19
The Evaluation Process
The ADSP-21469 EZ-KIT Lite evaluation system, as shown in
Figure 2-4, provides a cost-effective method for initial evaluation of the
ADSP-21462/21465/21467/21469 SHARC processors via a USB-based
PC-hosted tool set.
The ADSP-21462/21465/21467/21469 SHARC processors, which
are pin-compatible, have similar memory maps. Software develop-
ment for any of these devices can be performed on the
ADSP-21469 processor. Thus the EZ-KIT Lite evaluation system
may be used for any of these devices.
The EZ-KIT Lite includes an ADSP-21469 SHARC processor desktop
evaluation board along with an evaluation suite of the VisualDSP++ devel-
opment and debugging environment with the C/C++ compiler, assembler,
and linker. The evaluation suite of VisualDSP++ is designed to be used
with the EZ-KIT Lite only.
The EZ-KIT Lite also comes with a standalone debug agent board that is
removable to allow a user to plug in an external emulator. It also includes
sample processor application programs, a CE-approved power supply, and
a USB cable.
