The Design of a Machine Independent High Level Microprogramming Language

In this paper, HLML-C (High Level Microprogramming Language C) is proposed, which is independent of target machines and has similar strucrure to C language. The HLML-C operations are defined for a abstract machine which contains characteristics of various microarchitectures, and can extend to define a target machine's special operations for efficient microcode generation. A microprogram written in this language is translated into a machine independent intermediate language on abstract machine with the information of a target machine's resource usage and then microoperations of a target machine. The HLML-C compiler is implemented with yacc and C language on VAX-11/750 (4.3 BSD) computer. Through the various test microprogram applied to HLML-C compiler, their results are analyzed.
