【摘要】 在实时信号处理系统中,DSP+FPGA的系统架构具有较高的数据处理速度和较好的接口设计灵活性。提出一个DSP+FPGA架构的实时信号处理系统,分析该系统的存储器构成及工作原理,设计了该系统的PDT(peripheral de-vice transfer)传输方式,实现了DSP的EMIF口对高速数据的读写控制。更多还原

【Abstract】 A Real-time signal processing system with the structure of DSP+FPGA,specializes in high-speed data processing and has flexibility in its interfaces designing.In this paper,the author designed a Real-time signal processing system with the structure of DSP+FPGA,analyzed conformation of storage of the system and its principle of function,designed the PDT transferring mode of the system,and realized high-speed data’s read-write with EMIF upon the DSP.更多还原
