Title: David M Robinson - Innovator in Cache Coherency Protocols

Introduction

David M Robinson is a notable inventor based in Bellevue, WA (US). He has made significant contributions to the field of computer systems, particularly in the area of cache coherency protocols. His work has implications for multi-processor systems, enhancing their efficiency and performance.

Latest Patents

David M Robinson holds a patent for a "Cache coherency protocol for multi-processor computer system." This innovative protocol provides mechanisms for read/write, read-only, and transitional data states. It also includes a memory directory in main memory that indicates these states. The transitional data state is particularly important as it occurs when a processor requests a data block from another processor's cache, and the request is pending completion. During this time, all subsequent read requests for the data block are inhibited until the first request is completed. Additionally, the memory directory contains a field that identifies the processor owning the data block, which is crucial for determining the location of requested owned data.
