Abstract: Generally disclosed herein is an approach for a telemetry subsystem enabling the telemetry data to be collected and processed without the need to interrupt processing jobs being processed by processing cores. The telemetry subsystem may include one or more telemetry cores dedicated to telemetry data collection. Telemetry cores are configured to receive telemetry data from telemetry agents, processing cores, and other components of a system on chip (SoC).

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.
