Macronix DSP is a 16 bit programmable DSP coprocessor in the Nintendo GameCube\Wii\Wii U it was manufactured by Macronix. It has it's own ADPCM hardware decoder to off load the DSP. Audio Data is stored in Mem1 or Mem2 In Wii mode the clock speed has changed from 81MHz to 121.5MHz.
Macronix DSP microcode is written in assembly you will require a assembler to assemble your code. asnd & aesnd is the homebrew dsp microcode that exist in devkitpro for the Nintendo GameCube\Wii.
JAudio(JSystem) DSP microcode also seems to contain these types:
SRC_SQUARE_WAVE SQUARE_WAVE_25PCT SAW_WAVE PCM8 PCM16 DSP-ADPCM
