摘要
通过对异步传输模式 (ATM )理论研究和电力业务的分析 ,选择了IDT772 5 2和PM5 346芯片 ,设计完成了一种实用的ATM接口电路并用于多业务接入服务器 ,可解决目前多业务接入的实用性差和成本高等问题。基于嵌入式LINUX操作系统对硬件电路和驱动程序模块进行研发 ,并具体实现了驱动程序模块。
By researching the theory of ATM and analyzing the power services, a method to implement the ATM interface of multiple services access server is put forward The paper introduces the principle of ATM interface circuit based on IDT77252 and PM5346 in particular. Based on the embedded Linux platform the paper studies hardware circuits and driver modules, which are realized in detail.
