An on-chip memory management unit allows the digital signal processor and the control processor to share external ROM and RAM devices. The ROM bus width should be 16 bits, while the SRAM can be selected to be 8 or 16 bits wide. When using an 8-bit SRAM, fast type (static cache) should be selected as two SRAM cycles will be done in one ROM cycle duration. Running at 300 million operations per second (MOPS), the digital signal...
