ATSAM9708 Sound Synthesis

The ATSAM9708 is a 128-voice integrated synthesizer, integrating two PDSP blocks and a memory management unit (MMU). One PDSP block is a combination of a specialized 64-slot RISC-based digital signal processor (DSP), a general-purpose 16-bit CISC-based control processor (P16), a cache memory and an “intelligent” peripheral I/O interface. Both PDSPs are fully.
