From mame source eolith driver:

Sound: General MIDI Chipset QDSP 1000 MIDI Player (80c32 CPU)

The QDSP 1000 chipset (AdMos 9638R) it's also used on ADLIB MSC 16/32 CX4236B/37B soundcards, ESS Audiodrive 1869F soundcards, and ATC-6631W soundcards.

From mame source:

Sound CPU: 80c301/AT89c52

The GMS80c301 is an 80c31 (mcs51 compatible) so there's no need to write a new core.

Perhaps this helps:
