A High-Performance Heterogeneous Embedded Signal Processing System Based on Serial RapidlO Interconnection

摘要

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 emhedded 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 RapidlO interconnection to fulfil) 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 highspeed AD module, heterogeneous processing module including FPGA and CPU and RapidlO switch module. The system conform to Advanced Mezzanine Card (AMC) Standard and AdvancedTCA Standard and all modules aggregated by serial RapidlO. The system can perform up to 2Gsps sampling rate, up to 550MHz processing capability on FPGA and 15GHz on CPU and up to 80Gbits/s aggregate bandwidth. And finally applications such as system dataflow and control are presented.
