<p>A control store provides device control signals to a device controller. The device controller controls each selected operations of a device connected thereto. The control store comprises a programmable front end logic for generating a first plurality of operations control signal in response to a requested operation. Each operation control signal defines a type of control cycle desired to be performed by the device. A control store block stores a second plurality of information. The second plurality of information defines a predetermined condition of each of the device control signals in a timed sequence of a selected control cycle such that the device performs the requested operation. Both the programmable front end logic and the control store block are programmable permitting modifications to the control store to be made easily.</p> |
