Abstract
The technology generally relates to systems and methods for performing in-field testing of processing cores within a system-on-chip (SoC), so as to identify faults, including those associated with silent data corruption. For example, an SoC may contain operational cores and spare cores. An operational core may be selected for testing while a spare core is used to replace the tested core. In addition, a spare core may be used to replace an operational core that has been determined to be corrupted.
