A Multi-purpose VLSI Floating-point Array Processor

A 3x3 single instruction multiple data (SIMID) array processor for the IBM PC/AT is described. This array processor is a modified bus-connected architecture (MBOA) using TI's SN74ACT8847 64-bit VLSI floating- point units for processing elements, The array processor can operate in four different modes of operation : scalar, vector processor, full utilization, and simulated systolic. In full utilization mode, this array processor can sustain a 90 MFLOP computational rate.
