【应用笔记】使用FPGA为TI TMS320C6000做外设扩展与协处理器(FPGA Peripheral Expansion & FPGA Co-Processing with a TI TMS320C6000) 本应用笔记描述了外设和协处理器如何添加到德州仪器(Texas Instrument,TI)的TMS320C6000系列数字信号处理器件中去。 This application note describes how peripherals and co-processors can be added to Texas Instrument’s (TI’s) TMS320C6000 family of digital signal processing (DSP) devices. The hardware interface is a connection between TI's external memory interface (EMIF) and a first-in first-out (FIFO) buffer. In the Altera? Ateme EMIF reference design, a fast Fourier transform (FFT) co-processor and an LED peripheral provide examples of how a system can be developed using Altera development tools and architecture elements. The architecture provides flexibility to allow many types of peripherals and co-processors. The concept is demonstrated on Ateme's DMDK642 development board, which features a TI DM642 digital media processor and an Altera EP1C20 Cyclone? FPGA.
