REAL-TIME VALIDATION OF MICROCODE UPDATES

Abstract: real-time validation of microcode updates may include: executing a workload on at least one first processor having a first version of a microcode instruction set; executing the workload on at least one second processor having a second version of a microcode instruction set, wherein the second version of the microcode instruction set comprises an update of the first version of the microcode instruction set; and validating the second version of the microcode instruction set based on a comparison of output from executing the workload using the at least one first processor and output from executing the workload using the at least one second processor.
