数据的连续采集

The Implementation of Acquiring Data Continually

为了存储大量的连续采样数据,可以利用FPGA和SDRAM SO-DIMM(Small Outine Dual Inline MemoryModule)构成数据采集系统,关键技术是在FPGA中利用FIFO实现数据缓存。仿真结果证明该方案可以满足本文的设计要求,而且具有一定的通用性和灵活性。

In order to store a number of continual sampled data, FPGA and SDRAM SO-DIMM （Small Outline Dual Inline Memory Module） can be made use of to form an acquiring data system. Taking FIFO as data cache in FPGA is the key technique, The result of simulation proves that this method can satisfy the requirement of the design, and have universality and flexibility to a certain extent.
