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。
Through the theoretical analysis of asynchronous transfer mode (ATM) and the analysis of power services, we selected IDT772 5 2 and PM5 346 chips, designed and implemented a practical ATM interface circuit and applied to the multi-service access server, which can solve the problems of multi-service access Into the poor practicality and high cost issues. Based on the embedded LINUX operating system for hardware circuits and driver modules for research and development, and the specific realization of the driver module.
