N2 - A high-speed real-time digital signal processing system based on TI's multi-point DSP (TMS320C6474) is described. By using FPGA devices as control unit and switching chip and SRIO interface as the data input and output interfaces for DSP chip, the system has a lot of characters, including high signal processing power, simple input and output interface and huge memory capability. In the software implementation, through using optimization algorithm, including ping-pong data throughput, static memory allocation techniques and three core software synchronization mechanism, the system realize three-core DSP real time signal processing and calculating efficiency meet the design requirements. The successful application of the image signal process in a scientific research project show that it has good ability to fill the high speed digital signal process.
