1. 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.
