DTIC ADA159671: Performance Evaluation of the JRS

More Book Details

Description of the Book:

The purpose of this thesis was to evaluate the performance of microcode automatically generated from a high level language. The performance of the generated microcode was compared to the performance of Fortran code on the VAX 11/780 to see if any increase in throughput could be attained by using the microcoded version. The factors affecting the automatic generation of microcode: compaction, optimization, cost, and machine independence are discussed. This is followed by a definition of the testing areas, description of the tests, and a description of the performance evaluation methods. The tests showed that the automatically generated microcode does not always out perform Fortran. In general, the Fortran code was better for mathematical calculations while the automatically generated microcode was better for bit manipulation and sorting/searching type applications. Additional keywords: microprogramming; microinstructions, AMGS(Automatic Microcode Generating System). (Author
