Interconnection between DSP and FPGA Based on SRIO Protocol

For the large data amount and computing complexity of the high-speed image processing system with the DSP+FPGA structure,an interconnection structure between DSP and FPGA processors is put forword based on SRIO protocol,and MPMC is used to implement shared storage of the internal processors.By programming on both DSP and FPGA processors,transactions in the direct I/O module are finally achieved in SRIO protocol.The interface can transfer data at the speed up to 3.125 Gb/s.Experimental results show the method can provide stable and reliable data transmission between processors,realizing flexible and efficient real-time data exchange within system.
