Latest Patents
Kanamaru's latest patents include a cache system used in a magnetic disk controller adopting an LRU (Least Recently Used) system. This invention features a magnetic disk controller that incorporates a cache memory employing an LRU scheme in its replacement algorithm for cache blocks. It comprises a directory memory with LRU counter fields, a host system that issues read/write commands with an arbitrary LRU settling value, a directory search circuit, and a microprocessor. The directory search circuit is responsible for searching the directory memory in response to the read/write command from the host system. The microprocessor stores the LRU setting value in the LRU counter field of the hit entry of the directory memory or the entry corresponding to the replacement target cache block, based on the search results from the directory search circuit.
