The Design of the Parallel Arithmetic Unit in PEPE

As the need for solutions to high speed processing problems increases, new and novel architectures will be developed. PEPE is an attempt to solve a specific real-time problem with use of special purpose hardware. The Ballistic Missile Defense Advanced Technology Center in Huntsville, Alabama started development studies in the late 1960s for a processor to offload the ever increasing demands on a serial processor operating in a ballistic missile defense (BMD) environment. PEPE's design specifically addresses the BMD problem. It was designed to perform three basic functions previously allocated to a CDC 7700 system. They are: Correlation of new radar returns with current tracks Track prediction on all current tracks Scheduling on a radar time/power line, pulses to acquire more data on current or new tracks.
