中文摘要：
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585MBps。
英文摘要：
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.
