ABSTRACT:
A disk drive control system comprising a micro-controller, a micro-controller cache system adapted to store micro-controller data for access by the micro-controller, a buffer manager adapted to provide the micro-controller cache system with micro-controller requested data stored in a remote memory, and a cache demand circuit adapted to: a) receive a memory address and a memory access signal, and b) cause the micro-controller cache system to fetch data from the remote memory via the buffer manager based on the received memory address and memory access signal prior to a micro-controller request.
