Latest Patents

Takumi Nonaka's latest patents include:

1. **Cache-tag control method in information processing apparatus having cache, with error checking mechanism in cache tag**: This innovative method aims to provide a reliable cache-tag control system that can correct errors while maintaining high-speed operation. It features a true-tag with a parity code and a shadow-tag that possesses an inverted polarity, stored in separate addresses within a cache tag-RAM. This design ensures that both tags are checked for errors, and in the event of detection, usability of the error-free tag allows the system to make accurate hit decisions and update data promptly.

2. **Cache memory device**: This invention is aimed at enhancing processing speed through a cache memory device that incorporates a primary cache memory. The device consists of two primary ways, each retaining bits of Least Recently Used (LRU) information, and works effectively to determine which data has been accessed the least over time. A primary cache control circuit enhances the performance by optimizing the bits retained in the old way that has been accessed.
