Reconfigurable Computing Technology for Image Compression in the BayernSAT Mission
Abstract
The next generation earth-observation satellites will have significantly increased performance requirements. New advanced compression techniques like Bit- Plane Encoding and transformation steps based on wavelets are gaining importance. However, due to the small size of the space electronics market, the availability of devices capable to implement such algorithms is decreasing. This has motivated EADS-Astrium GmbH to search new processing technologies that can be transferred in the short term to reliable commercial space technologies. The emphasis is put on reconfigurable processing, since this is the only way to reduce risks and costs and assure the proper functionality of the satellite during its whole life. The eXtreme Processing Platform is a new runtime reconfigurable processor technology, An ESA study, with the name "XPP Applicability Study" was already carried out to prove the feasibility of this new technology and its superiority over different architectures being offered in the market. An important part of this study was also the transfer of the architecture to a radiation-tolerant semiconductor technology. The small satellite mission BayernSAT of the Technische Universitat Munchen will serve as a demonstration of the image processing capabilities of a new reconfigurable processing technology, the XPP, integrated in a configurable processor system based on the LEON Sparc processor.
