Latest Patents

One of Cornu's latest patents is titled "Processor unit resource exhaustion detection and remediation." This invention involves a performance monitor that provides cache miss stall and memory bandwidth usage metric samples to a resource exhaustion detector. The detector can identify conditions of last-level cache and memory bandwidth exhaustion based on these metrics. If both cache miss stalls and memory bandwidth usage are increasing, the detector reports a memory bandwidth exhaustion condition to a resource controller. Conversely, if cache miss stalls are rising while memory bandwidth usage is declining, it reports a last-level cache exhaustion condition. The resource controller can then allocate additional resources to address these issues.

Another significant patent is focused on "Technologies for cache side channel attack detection and mitigation." This invention includes an analytics server and monitored computing devices. The analytics server polls each device for analytics counter data generated by a resource manager. This data may include last-level cache or memory bandwidth information. The server identifies suspicious core activity and, if detected, deploys a detection process to the computing device. The device can then execute corrective actions, such as limiting resource usage by suspicious processes.
