Title: Doug Solomon: Innovator in Cache Coherence Technology
Introduction
Doug Solomon is a notable inventor based in Los Altos, California. He has made significant contributions to the field of computer architecture, particularly in cache coherence technology. With a total of 2 patents, Solomon's work focuses on improving data management within cache systems.
Latest Patents
One of Doug Solomon's latest patents is a method and apparatus for purging data from a middle cache level without affecting the corresponding data in a lower cache level. This innovation allows for the replacement of purged data with other data from a different memory address while maintaining the integrity of the first cache line in the lower cache level. The process involves ensuring that the first cache line is in a "shared state," which permits reading but not modifications. If modifications are necessary, a directory facility issues a purge to all caches containing the shared-state data, allowing the processor to request an exclusive-state copy. This method enhances the efficiency of cache management and data retrieval.
Another patent by Solomon describes a system-level cache line conversion, which facilitates the transition from a directory-based cache coherence model to a snoop-based cache coherence model. This innovation is crucial for optimizing cache performance and ensuring seamless data access across different processor levels.
