  • Publication number: 20250123844
    Abstract: Methods and apparatus for inhibiting branch prediction unit operations of a computer are provided. Program code is generated having instructions which inhibit branch prediction prior to a stable path being executed, the stable path being stable (e.g. with all instructions executed sequentially as they occur in memory) with high likelihood. The instructions when executed trigger such branch prediction unit inhibition. The instructions can be generated so as to have a high prevalence, length, or both, of stable paths.

  • Patent number: 12072749
    Abstract: Systems and methods for machine learning-based power capping and virtual machine placement in cloud platforms are disclosed. A method includes applying a machine learning model to predict whether a request for deployment of a virtual machine corresponds to deployment of a user-facing (UF) virtual machine or a non-user-facing (NUF) virtual machine. The method further includes sorting a list of candidate servers based on both a chassis score and a server score for each server to determine a ranked list of the candidate servers, where the server score depends at least on whether the request for the deployment of the virtual machine is determined to be a request for a deployment of a UF virtual machine or a request for a deployment of an NUF virtual machine. The method further includes deploying the virtual machine to a server with highest rank among the ranked list of the candidate servers.

  • Patent number: 11935309
    Abstract: This document discloses methods of training a classifier to identify traffic signal states in images captured be a vehicle. The vehicle can then use the identified states when making movement decisions when traveling in an environment. The system determines that a traffic signal is within a field of view of the camera (i.e., within an image). The system also receives a signal with signal phase and timing data for the traffic signal. The system processes the images to identify an image that includes the traffic signal. The system analyzes the signal data to determine a state of the traffic signal at the time of image capture, labels the image with a label of determined state, and passes the image and a label to a classifier in order to train the classifier.

  • Publication number: 20230315476
    Abstract: A method of branch prediction includes, in a pre-execute loop, loading a series of instructions leading to a load dependent branch (LDB) instruction including a load instruction, executing the load instruction to receive a part of a branch condition, computing a branch outcome of the LDB instruction based on the branch condition, and storing the branch outcome to a branch-outcome memory. Then, in a main loop corresponding to the pre-execute loop, loading the LDB instruction, reading the branch outcome from the branch-outcome memory, and executing the main loop based on the branch outcome. In some cases, the method, in the main loop, computes the branch outcome of the branch condition again.

  • Patent number: 11740906
    Abstract: A method and hardware system to remove the overhead caused by having stream handling instructions in nested loops. Where code contains inner loops, nested in outer loops, a compiler pass identifies qualified nested streams and generates ISA specific instructions for transferring stream information linking an inner loop stream with an outer loop stream, to hardware components of a co-designed prefetcher. The hardware components include a frontend able to decode and execute instructions for a stream linking information transfer mechanism, a stream engine unit with a streams configuration table (SCT) having a field for allowing a subordinate stream to stay pending for values from its master stream, and a stream prefetch manager with buffers for storing values of current elements of a master stream, and with a nested streams control unit for reconfiguring and iterating the streams.
