Development of Experimental Compilers to Generate Emulators for the BMD DDP Test Bed From High Level Language.

Abstract

The use of compilers to go from high level languages to microprograms is not commonplace. A few experimental compilers have been described but no support of this concept is provided by manufacturers of user microprogrammable computers. In this feasibility study two existing compilers accepting dialects of P1/1 were considered for generating microprograms for computers with a horizontally encoded control word format. One of the compilers which accepts the PLM language as input and produces quadruple intermediate text formats and DEC PDP 11 assembly language statements as outputs, was selected for modification to produce microprograms. A post processor is described which was added to this compiler to produce microcode for the DEC PDP 11/45 minicomputer. A performance analysis of this compiler concludes the report. (Author)
