用CPLD实现PCI总线仲裁器

Implementation of PCI bus arbiter using CPLD

介绍了PCI总线仲裁的工作机制,并且根据旋转优先算法用VHDL语言进行CPLD设计,通过作者实际研发项目WAS(无线应用服务器)单板的应用,论证了其可行性和稳定性。

The running mechanism of a PCI bus arbiter is described in detail. The CPLDdesigned with VHDL language based on rotate priority algorithm was applied. With the applicationof the development project——WAS (Wireless Application Server) in reality , the feasibility andstability of arbiter are validated sufficiently.
