Abstract:

The Workstation Communications simulator WCS is a personal computer based hardwaresoftware system for the interactive digital simulation point-to- point digital communications systems. The baseline WCS is hosted on an IBM PCAT microprocessor and is written entirely in FORTRAN-77. The enhanced WCS employs an additional optional single-board floating point array processor to perform the computationally intensive signal processing calculations. This report describes the initial implementation of the enhanced WCS utilizing a VORTEXAT array processors. The computational throughput gains experienced over the baseline WCS are consistent with expectations and are on the order of a factor of three. The throughput gain would have been considerably higher had it not been for the fact that the microcoded Gaussian random number generator did not function correctly and was not used. Further increases in computational throughput can be obtained through the optimization of the enhanced WCS software for use with the VORTEXAT.
