The transfer of multiple sectors of data between a hard disk drive and a computer data bus of a host computer is controlled by hardware within a computer bus interface circuit of a storage controller integrated circuit of this invention. Multiple sectors of data are transferred without intervention of a microprocessor that controls the operation of the disk drive containing the storage controller integrated circuit. The computer bus interface circuit 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. |
