Latest Patents

John W. Sias holds a patent for a "Method and apparatus for enhancing instruction level parallelism." This invention discloses a method and system for handling inline recovery from speculatively executed instructions. Each register is equipped with an E-tag, which indicates if an exception occurred during the generation of the value stored in the register, and an R-tag, which manages data flow dependencies in recovery mode. The recovery process involves re-executing those speculative instructions that are data flow dependent on a first excepting speculative instruction. This architecture and method provide efficient exception handling when combining control speculation, data speculation, and predication, resulting in substantially enhanced instruction level parallelism. He has 1 patent to his name.
