通用地震数据采集器EDAS-24GN中CPU数据收发方式
Data receiving-sending method in EDAS-24GN
摘要
Abstract
The data transformation between CPU and AD in earthquake acquisition system is usually through serial port or FIFO buffer. There are some questions existing in this method: many interruptions lead to lower CPU processing efficiency; transferring rate is slow and data will be lost when CPU is overloaded. A new data transferring method is used in EDAS-24GN. It is effective to solve the problems of previous method through SSC which is one part of AT91SAM9263 CPU. This new method has been verified that only several interruptions will be arose when more than 50 kB data is transferred and no data will be lost.关键词
