A high-performance heterogeneous embedded signal processing system based on serial RapidIO interconnection

The demand for high-performance embedded signal processing systems has expanded rapidly in recent years. As applications requiring faster computation capability, higher throughput bandwidth and more flexible interconnection, traditional embedded signal processing systems could not meet the demand of ever-increasing performance. The paper designs a high-performance heterogeneous embedded signal processing system based on the serial RapidIO interconnection to fulfill the next generation radar system. The system is designed based from aspects of computation capability of single processor, scale of parallelism in system, arrangement of memory architecture, interconnection topology and bandwidth. The system consists of three modules which are high-speed AD module, heterogeneous processing module including FPGA and CPU and RapidIO switch module. The system conform to Advanced Mezzanine Card (AMC) Standard and AdvancedTCA Standard and all modules aggregated by serial RapidIO. The system can perform up to 2 Gsps sampling rate, up to 550MHz processing capability on FPGA and 1.5 GHz on CPU and up to 80 Gbits/s aggregate bandwidth. And finally applications such as system dataflow and control are presented.
