The sound chip (Sony SPC700) which actually a separate processor is a 8 bit sound chip with a 16-bit program counter, but all of it's registers are 8-bit. Even though it is a 8 bit chip it doesn´t generate more than 4-bit ADPCM sound data. It has 64Kbyte memory and 8 stereo channels.

the sdd-1 and spc7110 were custom chips built onto some later snes carts that acted as decompressors for certain gfx data on these carts. both chips had little or no documentation and no-one up till now could figure out the compression algorithm for the sdd-1.
