SERIAL ROM BOOT

With ever increasing speeds of DSP devices such as the 'C5x, and the increasing demand for reduced form factors, as in HDD applications, there is a need for integrating the program memory into the DSP device. For volume production where the program code has been fully debugged and changes are not foreseen, then masked ROM is appropriate. However, for prototyping and preproduction evaluation, a programmable device is desirable, (i.e., a DSP with EPROM memory).

This document discusses how to use a serial ROM for minimum form factor storage of boot code. A code listing is included.
