Abstract: With the rapid development of semiconductor and integrated circuit technology, the integration level of microprocessor is becoming higher and higher. A strong debugging tool is very important during the development of large applications, especially when the bugs are too complicated to analyze. Based on the C8051 IP, the article presents an on-chip debug unit and integrates the debugging function into the MCU. With different configuration instructions, the on-chip debug unit can realize breakpoint instruction, address breakpoint, stop or single step execution procedures, data observation point, run to the cursor and other debugging functions.

Key words: integrated circuit, on-chip debug, C8051
