  • Patent number: 5235685
    Abstract: A data processing system is disclosed in which a plurality of high performance, intelligent, mass storage input-output devices are linked to a host controller by an input-output interface bus which is divided into three sections. Each section is completely independent of the other two sections and used for a different and specific purpose. One section is used to transfer commands and retrieve status information. A second section is used to handle device requests for data transfer and device signals for operation complete. The third section is used to transfer data to and from a device. Since the three sections are completely independent, simultaneous transfer of command control and data to different input-output devices or to a single input-output device can be performed.
