Macronix DSP is a 16 bit programmable DSP coprocessor in the Nintendo GameCube\Wii it was manufactured by Macronix. It has it's own ADPCM hardware decoder to off load the DSP. It stores raw DSP data in the 16 MB of ARAM along with audio data, but ARAM also can store extra data such as textures, animations, for example.
Macronix DSP microcode is written in assembly you will require a assembler to assembly your code into a binary file then you will need to convert it into a c array to compile with like devkitpro, engine, or whatever your project is.
