| 摘 要： | 针对ARM9处理器专用总线扩展时存在总线竞争以及WindowsCE系统下的应用程序不能直接访问外设物理地址等问题，以S3C2410处理器通过HPI接口扩展TMS320VC5402型DSP为例，提出了一种专用总线设计方法，并对防止总线竞争和WindowsCE系统下总线设备的虚拟地址编程访问进行了详细分析。

| Abstract: | In the process of special bus design for a peripheral to ARM9 processor, the system is broken down because of bus-competing, and the physical address can not be directly accessed by the programs in Windows CE. Based on the design of HPI between S3C2410 and TMS320VC5402, a method is presented in this paper for a special bus design. The ways of bus-competing and virtual address accessing are also analyzed. |
