Abstract :
Two software-based techniques for online detection of control flow errors were evaluated by fault injection. One technique, called block signature self-checking (BSSC), checks the control flow between program blocks. The other, called error capturing instructions (ECIs), inserts ECIs in the program area, the data area, and the unused area of the memory. To demonstrate these techniques, a program has been developed which modifies the executable code for the MC6809E 8-b microprocessor. The error detection techniques were evaluated using two fault injection techniques: heavy-ion radiation from a californium-252 source and power supply disturbances. Combinations of the two error detection techniques were tested for three different workloads. A combination BSSC, ECIs, and a watchdog timer was also evaluated.<>
