A Machine Independent Automatic Microcode Generation

This paper proposes a microcode generating system which automatically generates the microcode of various target machine by inputing the intermediate language (MDIL) from the machine independent HLML-C (High Level Microprograming Language C) language. The MOP's (Microoperations) which is modeled 7-tuples generate to extend MDIL by table driven method with the information of translation table for each target machine. As compaction being considered and the hardware resource of target machine used, the conflicts of hardware elements are removed possibly. This proposed system is implemented with C language and yacc on VAX-11/750 (UNIX 4.3 BSD).
