Latest Patents

One of Tendler's latest patents is titled "Performance monitoring based on instruction sampling in a microprocessor." This invention addresses the challenges of performance monitoring by introducing a microprocessor that includes a dispatch unit. The dispatch unit is designed to receive a set of instructions from an instruction cache and forward them to an issue queue when they are ready for execution. The inclusion of sampling logic allows for the selection of one instruction from the set for performance monitoring. This microprocessor also features a performance monitor unit that tracks the performance characteristics of the selected instruction during execution.

Another significant patent by Tendler is "Method system and apparatus for instruction tracing with out of order processors." This invention provides a method for instruction tracing in out-of-order speculative processors. It involves storing information related to the state of an instruction cache and a data cache in a trace storage device, along with the instructions fetched by the processor. This allows for the reconstruction of the instruction stream based on the stored information, ensuring that the state of the cache is known at all times during instruction fetching.
