Increasing information processing needs and data complexity of space exploration has motivated the constant development of higher speed DSP processor modules. These changes and the need to maximize the science data gathered and returned from satellite instruments has led to the development of a line of space qualified, DSP based spacecraft computers (DSP modules) at Southwest Research Institute. The DSP module family (SC-DSP) established at Southwest Research Institute (SwRI) forms an integral part of SwRI's SC-9, VME based, command and data handling systems. Included in the SC-DSP line are the space proven TMS320C30 based, SC-7 module, several module variants of the RTX2010 processor, and a radiation tolerant version of the Analog Devices 21020 in the newest SC-21020 DSP module. SwRI'S newest module (SC-21020) was developed to provide data handling functionality, while maintaining support for critical spacecraft control functions. The SC-21020 spacecraft computer utilizes these features coupled with high performance radiation hardened memories and the space proven VME bus.
