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 S-SMP. It is clocked by X2.
It has 128 registers (DSPRAM) that can be manipulated by the S-SMP, 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]
