摘要
在嵌入式系统的开发过程中,软件的调试工作是很必要的,而芯片本身所提供的硬件调试接口可以使调试的效率大为提高。本文在分析ARM7TDMI微处理器的JTAG接口的基础上,设计了TAP(Test Access Port)控制器。
It is necessary to debug the software in the development of embedded system and the debugging hardware supported by the microprocessor can excessively promote the efficiency of debugging. Based on the analysis of JTAG interface in the ARM7TDMI mi- croprocessor, the author finish designing the TAP controller.
