Title: The Innovations of Shumpei Kawasaki in Logical Cache Memory

Introduction

Shumpei Kawasaki, an inventive mind based in Palo Alto, CA, has made significant contributions to the field of computer memory management. With a total of four patents to his name, his work focuses on enhancing the efficiency of logical cache memory systems.

Latest Patents

Among his latest patents, Kawasaki developed methods for operating logical cache memory that retains logical and physical address information. In particular, his innovations address the challenges of cache misses in shared areas. The patents describe a mechanism where physical page information, corresponding to logical page information, is retained as a cache tag address within the logical cache memory. When a cache miss occurs, the system compares physical page information from the cache with the result of a search address translation by the Translation Lookaside Buffer (TLB). If the information aligns, the cache entry is processed as a cache hit, effectively halving the access frequency to the TLB and addressing issues related to synonyms—where the same physical address is assigned to different logical addresses. This inventive approach enhances memory handling efficiency significantly compared to conventional arrangements.

Career Highlights

Kawasaki has an impressive career, having worked with notable companies such as Hitachi, Ltd. and Hitachi Micro Systems, Inc. During his time at these organizations, he contributed to various advancements in technology, further establishing his reputation as an impactful inventor.
