Title: The Innovations of Masaru Koyanagi

Introduction

Masaru Koyanagi is a notable inventor based in Hadano, Japan. He has made significant contributions to the field of cache systems, holding a total of 2 patents. His work has been instrumental in enhancing the efficiency of data processing in computing systems.

Latest Patents

Koyanagi's latest patents include a "Cache system with a cache tag memory and a cache tag buffer." This innovative cache system comprises a cache tag buffer for storing a part of a cache tag memory. When a memory processing request is issued from a processor, a cache control means retrieves both the cache tag memory and the cache tag buffer. If a target cache block is present in the cache tag buffer, the cache control circuit accesses the cache data memory using information from the cache block without waiting for a retrieval result from the cache tag memory. Another significant patent is the "Cache control method and cache controller." This patent describes a cache controller that stores pre-set variables for pre-fetch block size and stride value. The cache controller receives an access request for the main memory from the processor and generates a pre-fetch request based on the access request and the variables. It then reads data from the main memory based on the generated pre-fetch request and writes this data to the cache memory.
