Latest Patents
Yoshikawa's latest patents focus on enhancing data transfer efficiency in multiprocessor systems utilizing shared cache memory. One of his notable inventions involves a method where each entry in a tag storage section of a cache memory holds a reference number field, alongside a tag address field, a valid field, and a dirty field. This reference number field is set during data writes and decremented after each read access. When the reference number changes from '1' to '0', the entry is invalidated without requiring a write-back operation. This innovation allows the cache memory to function as a shared FIFO, automatically deleting used data when employed for communication between processors.
