Abstract:
A peripheral system has one or more buffered control units connected to a plurality of peripheral devices. Operation times of the devices are marked by the buffer and controls which overlap device operations, queue device operations in a priority set of queues, and prioritize peripheral system operations. Plural specialized interconnections between each control unit and the devices include a preparatory connection for transfer of preparatory commands to devices, a tag or control connection for device selection, deselection and control and a data-command connection for signal transfers between a selecting control unit and a selected peripheral device.
