Latest Patents
One of his latest patents is titled "Ineffective Prefetch Determination and Latency Optimization." This invention involves a processor that initiates an L3 cache prefetch operation in response to a demand load during instruction processing. The processor randomly selects an L3 cache prefetch for tracking as a target prefetched instruction. It then initiates an L1 cache target prefetch operation and stores the resultant target prefetched instruction in the L1 cache. The processor analyzes the target prefetched instruction for effectiveness when a demand load arrives and determines the source of the prefetch data. If no demand arrives, it tests to see if the prefetched instruction has timed out in the cache, identifying the ineffectiveness of the prefetch operation. This innovation allows for the sampling of multiple prefetch operations at random, generating a history of prefetch effectiveness and enabling the reduction or removal of ineffective prefetch operations.
Another significant patent is the "Performance Monitor Unit for Sampling All Performance Events Generated by a Processor." This invention detects and records events in a processor using a performance monitor that samples events. The performance monitor receives performance event signals generated by the processor, indicating its current full event state. It includes a limited number of counters for counting only a selected subset of performance event signals. An event register intercepts these signals prior to counting, storing them as a single unit that represents the full set of available performance event signals.
