Latest Patents

One of Chang's latest patents is a method for identifying hard-to-predict branches to enhance processor performance. This innovative method and apparatus handle branch instructions within a source program by applying a set of heuristics to classify each branch instruction as either hard-to-predict or simple. The system implements a multi-heuristic branch predictor that includes a large, relatively simple branch predictor with many entries to accommodate the majority of branch instructions, alongside a smaller, sophisticated branch predictor designed for hard-to-predict branches. By effectively mapping these branches to the appropriate predictors, overall processor performance is significantly enhanced.
