ABSTRACT:
A host interface uses a state machine to control multiple sector transfers between a host computer and a physical storage medium, so that the idle time between sector transfers is minimized and not a function of the local microprocessor. A write sector counter is provided to keep track of the largest segment in a buffer memory so that demands for the local microprocessor is minimized. In addition, start counters pointing at the next sector in the buffer memory are provided to shorten response time in a read cache. BUSY and IRQ timers are provided to accommodate various implementations of BIOS's which may inadvertently clear a host interrupt to lead to a failure condition.
