Advanced Onboard Signal Processor

Abstract

The Advanced Onboard Signal Processor (AOSP) in a distributed signal processing computer under development for space radar, electro-optic and communications applications in the post-1985 time frame. The processor architecture is based on an arbitrary-topology network of identical processing elements specialized to perform signal processing and controlled by a distributed operating system. Both the operating system and applications programs are written in a high order language which is efficiently supported by the processing elements. Examples of communication signal processing are presented which show the suitability of AOSP for this application. The design has been validated by extensive simulation and is presently in the breadboard hardware phase.
