Latest Patents
Fueda's latest patents include an innovative input/output control apparatus that manages cache memory by utilizing a spare hash table for operations when the first hash table enters a synonym state. This invention addresses the challenges faced when an input/output request from a channel adapter results in a mishit on a cache. When a predetermined staging amount is reached by a device adapter, the cache is set into a hit status, allowing the channel adapter to be reactivated. This reactivation enables the channel adapter to execute input and output operations for both the cache and the staging in parallel. Additionally, he has developed a defective/alternating track management table that corresponds to track data stored in cache memory. This table includes addresses of defective and alternating tracks, along with flag information indicating the link state between them. This innovation allows for efficient retrieval requests, ensuring that the presence or absence of a registration in the hash table can be quickly judged.
