Title: **Innovative Contributions of Kazumasa Hamaguchi**
Introduction
Kazumasa Hamaguchi, an inventive force located in Yokohama, Japan, holds an impressive portfolio of 17 patents. His work focuses on enhancing data processing systems, particularly in network interconnections.
Latest Patents
Among his notable patents, Kazumasa has developed efficient methods and apparatuses for cache coherency in data processing systems. One significant invention involves a network where multiple nodes connect via a bus. This system employs tag information with state data to manage whether a data block is shared among nodes. When a write-access occurs on a data block marked as INTERNODE-SHARED, the system promptly requests the invalidation of the data block in the other node, thereby ensuring data integrity across the network.
Another recent patent highlights a novel approach to maintain consistency in cache memory data through arbitration techniques. Utilizing a light wavelength multiplexing connection, this system allows multiple nodes to communicate simultaneously using various wavelengths. The nodes can relay information to an arbiter, which manages the data transfer and ensures that each node updates its cache appropriately based on the data received.
