The continuous evolution of communication satellite platforms demands the use of modern approaches to system design. A system-on-a-chip realising the main functions of an on-board computer is an important step towards further minituarisation of small satellites. This paper describes a single-chip implementation of a simplified version of a Surrey Satellite Technology Limited (SSTL) on-board computer. The specification of the system and a prototype based on a XILINX Virtex FPGA are discussed. Synthesis results of the microprocessor and peripheral IP cores are reported.
