The SAM9707 is a highly integrated sound processor studio that combines a special-ized high-performance RISC-based digital signal processor(synthesis/DSP) and ageneral-purpose 16-bit CISC-based control processor on a single chip. An on-chipmemory management unit (MMU) allows the synthesis/DSP and the control processorto share external ROM and/or SAM9707RAM memory devices. An SAM9707 intelligent peripheral I/Ointerface function handles other I/O interfaces, such as the ISA PC bus, the on-chipMIDI UART and the codec control interface, with minimum intervention from the con-trol processor.
