<p>The transfer of multiple sectors of data between a hard disk drive (220) and a computer data bus (215) of a host computer (210) is controlled by hardware (250, 260) within a computer bus interface circuit (234) of a storage controller integrated circuit (230) of this invention. Multiple sectors of data are transferred without intervention of a microprocessor (221) that controls the operation of the disk drive (220) containing the storage controller integrated circuit (230). The computer bus interface circuit (234) of this invention not only automatically transfers data between the computer data bus and the computer bus interface circuit but also generates status information, generates interrupts to the host computer, and updates task file registers.</p> |
