Abstract
Different cores of a multicore processor are used to provide diagnostics of sophisticated hardware without full redundancy by static assignment of the cores during individual cycles of the control program and comparison of the outputs. A method of automatically generating diverse programs for execution by these cores may modify one program to compile two different instructions without functionally changing that program through the use of DeMorgan equivalents and diverse compiler optimizations.
