The Cesar Computer Architecture The Fastest Ers-1 Sar Processor In Europe

This paper describes, briefly, the implementation of a fast computer system capable of processing one lOOXlOO km ERS-1 S A R Fast Delivery product in 2 minutes. The development work is based on the Cesar computer system installed at the Troms0 Satellite Station in Norway. The paper describes the system in terms of architecture, programming environment and implementation of the SAR algorithm. The architecture introduces a programmable hardware implementation approach to algorithms through high order library functions, callable from a Unix environment. Parallelism with no communication overhead is achieved, providing high performance in vector computations.
