| 摘 要： | 对于嵌入式折反射全景视频处理系统，由于计算量大，一般采用多处理器协同的结构，但在该结构下多个处理器之间需要进行高速的数据通信。该文提出一种基于DSP+FPGA架构的双核高速数据通信方法，该方法通过基于地址总线的控制指令编码解析方法协同双核工作，通过逆向波形分析和基于乒乓缓存的间接DMA通信方式，实现DSP与FPGA之间的双核DMA数据通信。实验结果表明，使用上述方法实现的DSP与FPGA之间数据通信速度高达585 MBps。

| 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. |
