S-DSP
From SnesLab
S-DSP in region D4 of the jwdonal schematic
The S-DSP is the digital signal processor. It produces audio for the DAC and is controlled by the SPC700. It is clocked by X2.
It has 128 registers (DSPRAM) that can be manipulated by the SPC, some of which serve no hard-wired purpose and can be used as general-purpose RAM.
The highest sound frequency that the S-DSP can produce is 16kHz, because of the 32kHz rate that sample-points are output. [1]
