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.
