ABSTRACT:
A method and system for improving fetch operations between a micro-controller and a remote memory via a buffer manager in a disk drive control system comprising a micro-controller, a micro-controller cache system having a cache memory and a cache-control subsystem, and a buffer manager communicating with micro-controller cache system and remote memory. The invention includes receiving a data-request from micro-controller in cache control subsystem wherein the data-request comprises a request for at least one of instruction code and non-instruction data. The invention further includes providing the requested data to micro-controller if the requested data reside in cache memory, determining if the received data-request is for non-instruction data if requested data does not reside in cache memory, fetching the non-instruction data from remote memory by micro-controller cache system via buffer manager, and bypassing cache memory to preserve the contents of cache memory and provide the fetched non-instruction data to micro-controller.
