Method and apparatus for accelerating communication between controllable devices

A method to accelerate data transfer between a control processor and a plurality of controllable devices attached to a control device, the controllable devices receiving data from a master processor, the controllable devices further having an addressable memory location and an output, the method comprising the steps of:

• allowing the control processor to decode at least one address from the master processor corresponding to predetermined addressable memory locations;
• transmitting the data to each controllable device in a single write operation;
• and
• enabling the control processor to control selected controllable devices to transfer the data to the control device in a second write operation.

An apparatus for enhancing data communication between controllable devices, the apparatus comprising:

• a first controllable device programmed to decode an address from a control processor;
• and
• a plurality of second controllable devices receiving data from the control processor in a first write operation, each second controllable device adapted to generate an output corresponding to the data, each second controllable device coupled to the first controllable device,
• the first controllable device transmitting the decoded address to each second controllable device in the first write operation, each of the plurality of second controllable devices generating an output signal corresponding to the data in a second write operation.
