Description: Computer resources on military and telecommunications satellites are being over-tasked more than ever      before, and the increasing shift to onboard signal processing will only compound the problem in the future.      Space-based multiprocessor computer systems linked by high speed interconnect networks offer one      possible solution to this ever expanding problem. Gallium arsenide (GaAs) integrated circuits using      metal-semiconductor field effect transistors (MESFETs) offer very high speed operation, reduced power      consumption, and inherent radiation tolerance, which make them ideally suited to the harsh space      environment. The design, simulation and layout of an 8 x 8 non-blocking crosspoint switch implemented in      GaAs two-phase dynamic FET logic (TDFL) is presented in this thesis. The design of the TDFL      crosspoint switch given here is a modification of a crosspoint switch design that uses GaAs direct-coupled      FET logic (DCFL). Design specifics of working with GaAs are presented first, followed by detailed      descriptions of the DCFL and TDFL crosspoint switches, and finally, an analysis of the advantages and      disadvantages of dynamic logic over static logic is presented. The TDFL crosspoint switch presented here      could easily be modified to serve as a one gigabit per second serial interconnect for future space-based      multiprocessor computer systems.
