Abstract : A user microprogramming capability was implemented on AFIT's HP 21MX RTE-III computer system. The AFIT computer will be used to support student research in microprogramming projects involving real time digital signal processing and special time critical programs for military environments. This study further looks at a specific microprogramming technique to tailor application programs for improving a programs execution time. A feasibility study to analyze program activity for microprogram improvements is done for the fast Fourier transform. The Bit Reversal sorting routine is microcoded to demonstrate the technique. Response of the FFT programs is analyzed using an activity profile generator program, and the difference in execution speed of the programs with and without the microprogrammed bit reversal routine is measured and compared.
