摘要
在高速信号采集回放系统中,数据量非常庞大,传统的数据采集方式不能胜任。给出了一种基于ADSP-BF549的数据采集回放实现方案,结构简单、完全适合大存储量、高实时性的要求,并且成本较低。同时还对关键模块DDR SDRAM的地址和片选信号扩展进行阐述。
In high-speed sampler & replayer system, the datum is very big, and the traditional sample way can't be competent for this. The high speed data acquisition system based on the ADSP-BF549 is discussed.The system hardware circuit is very simple and its function can satisfy the requirement with low cost.This article also illustrates to the pivotal mode such as the enlarging of the address and CS signal of DDR SDRAM.
