基于FIFO的A/D与DSP之间接口的设计

Interface Design between A/D and DSP based on FIFO

基于FIFO以DSP数字信号处理芯片TMS320VC5402作数据处理器,拟定结合高速模数转换器AD9244、先进先出缓冲存储器芯片IDT7205构成的高速数据采集系统的设计方案。设计中主要体现FIFO的缓存作用,使FIFO能够在A/D于DSP之间充当媒介,较好的完成数据传输。

The design is based on FIFO which applies DSP digital signal processing chip TMS320VC5402 as a data processor,combined with highspeed transformer AD9244 with the high-speed data acquisition system constituted by advanced buffer memory chips IDT7204.Design mainly embodies the FIFO buffer action,makes the FIFO be a medium between A/D and DSP,and better complete data transmission.
