一种新型高速大容量非易失性数据采集系统

A New High-rate Non-volatile Signal Sampling System

提出了一种多通道非易失性高速实时大容量数据采集系统的解决方案。该方案采用并行SDRAM和FLASH作为存储介质,利用DSP、FPGA技术,实现了在每通道10MHz采样率下、4通道的实时采样,并满足了系统数据非易失和循环存储的要求。

Based on the application of DSP ＆ FPGA technology, a new design is developed to meet the demanding requests： high rate, real time, non-volatile and loop storing. By analyzing the system characters, this paper provides the method of associate SDRAM and FLASH to solve the problem.
