摘要： Disclosed embodiments relate to a prefetcher for delinquent irregular loads. In one example, a processor includes a cache memory, fetch and decode circuitry to fetch and decode instructions from a memory; and execution circuitry including a binary translator (BT) to respond to the decoded instructions by storing a plurality of decoded instructions in a BT cache, identifying a delinquent irregular load (DIRRL) among the plurality of decoded instructions, determining whether the DIRRL is prefetchable, and, if so, generating a custom prefetcher to cause the processor to prefetch a region of instructions leading up to the prefetchable DIRRL.

摘要： Methods and apparatus relating to reducing switching noise and improving transient response in voltage regulators are described. In an embodiment, one or more pulses are inserted into an output waveform of a voltage regulator. The one or more pulses introduce multiple frequencies into the output waveform of the voltage regulator (e.g., to reduce acoustic noise). In another embodiment, the output voltage of a voltage regulator is modified in response to comparison of the output voltage with at least one of a plurality of threshold values. The plurality of threshold values includes an upper trigger point voltage value and a lower trigger point voltage value. Other embodiments are also disclosed and claimed.

摘要： In one embodiment, a processor comprises a processor optimization unit. The processor optimization unit is to collect runtime information associated with a computing device, wherein the runtime information comprises information indicating a performance of the computing device during program execution. The processor optimization unit is further to receive runtime optimization information for the computing device, wherein the runtime optimization information comprises information associated with one or more runtime optimizations for the computing device, and wherein the runtime optimization information is determined based on an analysis of the collected runtime information. The processor optimization unit is further to perform the one or more runtime optimizations for the computing device based on the runtime optimization information.
