Title: Innovations of John R Hattersley
Introduction
John R Hattersley is a notable inventor based in Saugerties, NY (US). He has made significant contributions to the field of computer systems, holding a total of 3 patents. His work primarily focuses on advancements in multiprocessor systems and dynamic address translation.
Latest Patents
One of his latest patents is for a "Multiprocessor system with distributed memory." This invention describes a parallel computer system that comprises multiple high-level processors interconnected through a cross-point or cross-bar switch. An adapter is included between each processor and the switch, facilitating protocol processing to manage the switch, transfer pages, and schedule transmissions among the processors. The protocol employs typed or tagged buffer management, allowing clients to bind the semantics of messages being sent or received, which specifies behaviors during message packet transmission.
Another significant patent is for "Multiple virtual address translation per computer cycle." This invention introduces dynamic address translation structures capable of handling multiple address translations for the same processor within a single cycle. It utilizes a plurality of directory look aside tables (DLATs) accessed in parallel by separate virtual address generators. The invention addresses the challenge of generating the same address multiple times by employing 'shadow' DLATs, which are copies of the original DLATs, ensuring uninterrupted translations.
