Title: Innovations by Joseph A. Petolino: Pioneering Solutions in Computer Processing
Introduction
Joseph A. Petolino is an accomplished inventor based in Palo Alto, California. With a remarkable portfolio of 12 patents, he has made significant contributions to the field of computer processing. His innovative methodologies have paved the way for more efficient handling of branch instructions and cache management.
Latest Patents
One of Petolino's latest patents is titled "Fast handling of branch delay slots on mispredicted branches." This invention presents an apparatus and method designed to efficiently manage mispredicted branch instructions in processors featuring multiple instruction execution pipelines. When a mispredicted branch occurs, all following instructions, including the branch delay slot instruction, are cleared from the pipeline. If the delay slot instruction is to be executed, it is reissued to the pipeline, enhancing processing speed and efficiency.
Another notable patent is focused on a "Method and apparatus for solving the stale data problem occurring in a direct mapped, write-through virtual data cache." This invention addresses the issue of stale data in caches by employing a store allocate policy. The hardware mechanism ensures that a cache location linked to multiple virtual addresses does not become outdated compared to the main memory. By implementing this policy with a write-through virtual cache, any store miss triggers an update of the cache with data from main memory, thus maintaining data integrity and overcoming the stale data challenge.
