Abstract : A fast Fourier transform program has been developed and run on a simulation of the Burroughs D-Machine processor. This program was developed to gain insight into the use of microprogrammed structures for signal processing applications and to serve as a reference 'benchmark' during the development, evaluation, and application of programmable signal processors at the Naval Research Laboratory. The D-Machine simulator and a companion translator program have been written in Fortran to run on the Control Data Corporation's Kronos time-sharing system. This action was taken because of a paucity of software support for the D-Machine itself and because the simulator provides debugging features not found in hardware. The time-sharing terminal was also more accessible. Several of the test spectra which have been calculated are described. For reasons of scarcity of registers and lack of concurrency, the D-Machine is deemed poorly suited to signal processing applications. (Author)
