嵌入式ARM 软、硬件调试技术依赖于ARM 处理器调试硬件,本文在分析JTAG 边界 扫描结构的基础上,介绍了EmbeddedICE、嵌入式跟踪等实时调试技术,并给出了一个嵌入式调试开发系统的实例。 关 键 词:ARM JTAG EmbeddedICE 嵌入式跟踪 Abstrct:The debug technology for embedded software and hardware of ARM depends on the ARM processor’s debug hardware. First analyzing the structure of JTAG boundary-scan circuit, this paper introduced the debug technology of EmbeddedICE,Embedded trace and so on. In the end,an embedded debug development system is illustrated as an example. Key word:ARM JTAG EmbeddedICE Embedded Trace
