The SAR system framework which is used on space device is firstly presented and analyses were conducted on this framework. The function of real time processing could not be realized by available chips, it is necessary and urgently to research high performance multi-core processor. Then, a new heterogeneous multi-core SoC （System on a Chip） which is designed for SAR radar signal processing is introduced. The advanced technology of network on chip（NoC） is adopted in the heterogeneous multi-core SoC, and multi-layer mesh buses are integrated in it. There are two transfer modes supported by the bus： dynamic transfer used for data packets and static transfer used for data stream. Finally, the SoC compares performance and power with other traditional DSP, and the processing result is given.
