Description

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 spe-

cialized 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 independent and share the same external memory

through the MMU.
