A block transfer data bus having two separate paths, with each element coupled to the bus having the ability to arbitrate for use of one or the other or both of the bus halves. Each bus half includes an address/data bus portion for sending/receiving the data and addresses. A separate control bus portion for each bus half provides certain status signals and a code indicating the type of data on the address/data bus. An arbitration bus provides data request signals from each element to a central arbiter. In addition, a separate grant signal associated with each bus half is provided back to each element from the arbiter along the arbitration bus. A line on each control signal bus indicates whether or not the bus half is busy.

Dual channel data block transfer bus

An improved interface system based in part on the SCSI standard is provided. A single cable data bus simultaneously transfers several bytes of information between two devices. The interface system transfers multiple-byte commands, messages, status information or data in a single parallel transfer. A microsequencer is provided to permit data transfers across the interface without requiring burdensome attention from a processor in a device involved in the transfer.
