A straightforward set of short and simple benchmarks has been used to examine the relative performance of a wide range of mainframe, mini, and micro systems. Comparable sets ot BASIC, Pascal. FORTRAN and Structured Algol codes are given In a series of Tables and Figures. Special attention has been paid to the role of additional processors to assist In the execution of the benchmark codes. These Include a 6809 used to accellerate APPLE-Pascal 1.1 p-code and an AMD 9511 to accelerate BASIC-E and Structured Algol semi-complied code. Two AMD 9511 versions of MicroSoft and FORTRAN FORLIB are included. The overlap In performance of mainframe, mini. and micro systems is illustrated. The major conclusion Is that special attention should be paid to high speed Interpreters for semi-compiled commercially-available software products as a major thrust towards a transferable set of user environments at different levels of execution speed.
