Real-time SAR processing requires high computational power. At the Laboratorium fur Informationstechnologie a parallel DSP called HiPAR-DSP 16 was developed, which is optimized for image processing algorithms. In this paper we present a compact multi-DSP board utilizing the HiPAR-DSP 16. The board can deliver a performance of up to 15 GOPS, has a volume of 160 X 230 X 20 mm, and consumes less than 20 W. The first version of the board is used for filtering of SAR data to show the capabilities of the system. An estimation showed that our board can process an wk algorithm with a rangeline length of 4096 samples and a PRF of 600 Hz in real-time.
