Loop Storage Based High Speed Data Acquisition System

环形缓冲区结构的实时数据采集系统具有很多优点，本文介绍环形缓冲区的基本原理，使用ＳＲＡＭ芯片实现了存储区的环形结构，设计了一个实时高速数据采集系统，实现了数据的高速采集与传输，极大地提高了系统的工作效率。

A real time data acquisition system with loop buffers has many advantages. This paper describes the construction of the SRAM based loop buffer and the implementation of a real time high speed data acquisition system by using this kind of loop buffer. The system is successfully used in the design of ultrasonic flaw detectors.
