摘要: A design method of embedded OCD (On-Chip Debugging) based on Intel 8051 MCU architecture is proposed. The module named E-OCD-SFRB (Enhanced with SFR (Special Function Register) Breakpoint Function) integrated into an existing core, implementing several debugging function. we proposed able to switch from running mode and conveniently by controlling the enable port also enables core in additional SFR. function breakpoint added, so could trace particular SFR, this reinforcement exiting methods. principles E-OCD-SFR_B detailed implemental simulation solution EDA platform are presented validated. result indicates completely observing achieved without any effect original functions system.
