Abstract As the huge computational loads of panoramic video processing, most of the embedded panoramic video processing system are based on multi-cores. The problem of high-speed data communication between multi-cores must be solved. A high-speed data communication method between DSP and FPGA is proposed. In order to realize high-speed data communication, the address-bus is used to transport commands, the wave of data communication between dual-cores in DMA mode is analyzed and simulated. The experiments show that the data transmission speed is up to 588 MBps between DSP and FPGA by using those methods.
