At the Laboratorium für Informationstechnologie the HiPAR-DSP 16, a parallel digital signal processor (DSP) optimized for image processing algorithms, has been developed. We present a design of a compact multi-DSP board utilizing the HiPAR-DSP 16. Two boards were implemented: an application development board with a PCI interface and a board for SAR processing. With a computational power of up to 15 GOPS this board is suitable for real-time SAR processing, as an estimation for an ωk algorithm (range line length of 4096 samples, PRF of 600) shows. A volume of 160×230×20 mm3 and a power consumption of less than 20 W enables on-board integration. The first version of the board is used for filtering of SAR data to show the capabilities of the system
