| Abstract: | The paper presents an on-chip debug system based on JTAG standard for embedded microprocessors.With little hardware overhead,the debug system,which is based on JTAG standard,can give some powerful debug functions.For example,setting instruction/data hardware breakpoints,setting single step execution mode,monitoring the registers and memory,programming on line and configuring microprocessor's execution state can all supplied by this debug sys-tem.In this paper,firstly it introduces the debug system for embedded microprocessors,then it introduces the whole de-bug system including hardware,software and interface features,and finally it gives some practical data analysis. |
