摘要
基于uClinux操作系统的嵌入式纸币识别系统是当前纸币识别系统开发的一个重要方向:以μClinux为中心.结合S3C4510B的特点.在软件和硬件达到最佳平衡的基础上.重新设计了嵌入式纸币识别系统;为使μClinux能满足纸币识别系统的实时性要求.通过细化时钟粒度来减少任务响应时间的方法.改进了μClinux的实时性;试验表明.利用改进的μClinux设计的纸币识别系统可以满足要求。
The development of embedded bill acceptor system based on the operation system of μClinux is recently a significant way. An embedded bill aeeeptor system, on the foundation of keeping optimum balance between software and hardware, is redesigned with adopting μClinux and combining the characteristic of S3C4510B. In order to meeting bill acceptor system＇s request of real-time, a method is brought forward, through fining-grain timer to reduce the task response time, Shown in experimentation, the ability of Embedded bill aeeeptor redesigned by using the real-time μClinux can meet the request.
