Latest Patents

One of his latest patents is titled "Instruction and logic for run-time evaluation of multiple prefetchers." This invention involves a processor that includes a cache and a prefetcher module designed to select information based on a prefetcher algorithm. The prefetcher algorithm selection module is equipped with logic to select a candidate prefetcher algorithm, determine and store memory addresses of predicted memory accesses, and evaluate whether the determined cache lines match the stored memory addresses. Additionally, it adjusts the accuracy ratio of the candidate prefetcher algorithm and compares it with a threshold accuracy ratio to decide on its application.

Another significant patent by Chuang is "Identification of software phases using machine learning." This invention allows a computing device to execute an application with multiple phases while collecting performance data indicative of various performance attributes. The device merges data from a processor performance monitoring unit with data from the operating system, partitions the performance data into cluster models, and applies a classification algorithm to select the model with the lowest misclassification rate. This process enables the scheduling of compatible phases of software applications based on the selected cluster model.
