TMS320C5x DSP STARTER KIT USER'S GUIDE

Memory1.3 MemoryThe ’C5x DSK is one of the simplest ’C5x DSP application boards. Eventhough no external memory is available on the board, the 10K on-chip RAMof the ’C50 provides enough memory for most DSP application programs. Thekernel program is contained in the 32K, 8-bit PROM. The PROM is only forDSK boot loading and cannot be accessed after boot loading, as this portionof the on-chip memory is reserved for the kernel program.
