The use of a Restricted Instruction Set Computer (RISC) architecture, differing from the typical Von Neumann serial processing approach, allows simultaneous pipelining and processing of non-dependent data functions in a multiple processor (co-processor) environment. This approach is advanced by the use of multiple arithmetic execution units within one such co-processor. This co-processor is the Engineering Scientific Accelerator Floating Point Unit (ESA FPU) used in mid-range pipeline processors. This simultaneous execution is accomplished as described in the following. Illustrated in Fig. 1 is a simplified configuration of the mid- range pipeline processor.
