Design of Structure of Debugging Software in CPU Based on JTAG
It is important to own the capability of debugging application and system software and multitasking system in the design of microprocessor at present. In this paper, we proposed a debugging structure based on JTAG port and combined with boundary-scan technology and interrupt system, which can allow users to debug software procedure by the debugger which is connected to JTAG port. It is easy to form a standardized structure and applicable to all general-purpose CPU and only increases the difficulty of the circuit logic design.
