摘要
本文利用在Ａ／Ｄ转换器与微处理零之间建立公用双端口随机存贮器，并使Ａ／Ｄ转换器的连续数据采集和存贮与微处理器的运算处理并行工作，从而既提高了对多参数的巡检速度，又使得快速Ａ／Ｄ转换器在连续数据采集时其本身的转换速度得到充分的发挥。
In this paper,the design principle is to built one public two-port RAM betweenA/D converter and microcomputer, which make the sequence data acquistion of the A/Dconverter and the algorithm of the microcomputer work parallelly. This system not oulyimproves the multi-parameter cyclic detecting speed, but also makes the quickconveder’s speed fully used. It also provides the practical circuit diagram.
