Abstract
In a disk drive storage system, an interface apparatus for controlling the transfer of sectors of data between a host processor and a buffer within the storage system in response to READ and WRITE command issued by the host processor. The apparatus comprises a Byte Count State Machine for controlling the transfer of a sector of data between the host processor and the buffer, an Update Task File State Machine for counting the sectors transferred by the Byte Count State Machine and generating the sector address of the next sector to be transferred by the Byte Count State Machine, a Read State Machine for controlling the processing of all READ commands and a Write State Machine for controlling the processing of all WRITE commands.
