Assumptions about our system May have transient errors Check possible errors with given verification code Check verification code in chunks rather than for each instruction To be run on SimpleScalar
3
Models to compare with Standard system Doesn ’ t have transient errors Assumed to have 100% performance A system that executes each instruction twice and detects transient errors Assumed to have a little more than 50% performance
4
Measurements of system Inputs Rate of Errors Size of Epics Varying Programs Others(?) # of Components Code sizes Outputs Performance False Negative prob. False Positive prob.
5
Steps of comparison Source code (Possibly with VC) Standard gccour gcc Standard codeOur code + VC Normal CPUOur CPU Code Size Comparison Performance False negative False positive Comparison
