Control Flow Detection Based on Path Tracking
Jiang Cheng · Jisuanji gongcheng · 2009
Hardware transient faults can cause control flow errors and corrupt the normal execution process by altering the operand and opcode of instructions.Aiming at the program control flow errors caused by hardware transient faults,this paper proposes an instruction-level control flow detection method to tracking program execution path.Experimental results of faults injection indicate that the average value of fault detecting rate of this method is 97.8%,and the average memory overhead and performance overhead are only 83.2% and 52.9%.
