Real-time Multi-channel Vision Processing Based on DSPFPGA

摘要

In order to realize digital image sequence processing for multi-channel vision in real-time simultaneously, a hardware system with FPGA&DSP is designed. In the system, two ZBT SRAM chips are used as the input and output cache for high data transferring. A FPGA chip is responsible for the core logic controlling and multi-channel video synchronous. Digital videos are sent to the processing module by Camlink bus. Data are exchanged by EMIF and McBSP between FPGA and DSPs. EDMA is used for data transferring between SRAM in FPGA and ZBT SRAM. The QDMA is used for 2D data transferring to 1D into DSP cache. Tasks are assigned to chips by μC/OS on master DSP. All this together, real-time data sampling and processing for multi-channel vision was realized.
