ABSTRACT:
One embodiment disclosed relates to a method of compiling a program to be executed on a target microprocessor. A cycle is identified during which a functional unit would otherwise be idle. A diagnostic operation is opportunistically scheduled for execution on the functional unit during that cycle, and a comparison is scheduled to compare a result from executing the diagnostic operation with a corresponding predetermined result.
