Interactive communication system simulation on a high-speed PC workstation

The design, operation, and capabilities of a workstation-communications-simulation software system (WCS) for interactive simulation of point-to-point digital communication links is described. The system is based on Fortran-77 and is hosted on an IBM PC/AT or compatible microcomputer. At the heart of the system is a single-board floating-point array processor that provide approximately three orders of magnitude increase in computational throughput over operations performed in the AT alone. A description is given of how a unique method of interfacing to a PC host allows considerable flexibility in partitioning a simulation problem for execution on an attached processor. The WCS system is a highly graphics-oriented system using the latest advances in interactive color workstation technology.<
