Macronix DSP is a 16 bit programmable DSP(Slave Processor) 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. 
16 MB of ARAM stores PCM\ADPCM, but ARAM also can store extra data such as textures, animations, data, for example. 

Macronix DSP microcode is written in assembly you will require a assembler to assemble your code. asnd & aesnd is the homebrew dsp microcode that exists in libogc for the Nintendo GameCube\Wii, can mix up to 64 channels(AX\JAudio) and 16 or 32 channels(ASnd\AESnd) respectively in software.

JAudio(JSystem) DSP microcode also seems to contain these types
 SRC_SQUARE_WAVE
 SQUARE_WAVE_25PCT
 SAW_WAVE
 PCM8
 PCM16
 DSP-ADPCM
