Memory Management Unit (MMU)

The Memory Management Unit (MMU) block allows external ROM/Flash and/or internal 32K x

16 RAM memory resources to be shared between the synthesis/DSP and the P16 control pro-

cessor. This allows a single device (i.e. internal RAM) to serve as delay lines for the

synthesis/DSP and as data memory for the P16 control processor.
