A Microprogram Generator System (MPG) is a processor for Microprogram Generative Language (MPGL). MPG provides the facility of generating efficient object microprograms from higher level microprogramming language in a machine-independent fashion. This paper evaluates MPG and MPGL from several aspects: efficiency of object microprograms, generality and naturalness of MPGL, correctness, effectiveness, and machine independence of MPG procedure. For this purpose, experimentations are made for diffrrent types of machines and microprograms. Two target machines, HITAC 8350 and HP 21OOA, were chosen, in that HITAC 8350 has horizontal type microinstructions whereas HP 2100A has vertical ones. For each machine, four microprograms were wrritten: 1) Positive integer multiplication 2) Square root3) Conversion of arithmetic expression to reverse polish notation 4) Elementary function evaluation algorithm, CORDIC. Each microprogram was compiled and logically simulated by MPG. The experimental results show that MPG is applicable to different types of machines and that, if coded carefully, object microprograms are as efficient as hand-coded microprograms.
