Experiments in Automatic Microcode Generation
June 1983 (vol. 32 no. 6)
pp. 557-569
R.J. Sheraga, JRS Research Laboratories Inc.
A procedure is described which permits applications problems coded in a higher level language to be compiled to microcode for horizontally microprogrammed processors. An experimental language has been designed which is suitable for expressing computationally oriented problems for such processors in a distributed processing environment. Source programs are compiled first to a machine independent intermediate language and then to a machine dependence form consisting of elementary microoperations, with optimizations performed during each step. The microoperations are then compacted into executable microinstructions for a specific target machine. The procedure has been implemented for experimental purposes and used to compile several different types of applications programs. The experimental results are presented with an interpretation and analysis, along with recommendations for future study.
