A generic device controller unit system ( 10 ) includes a generic "true real time" peripheral device controller and a data and protocol communications interface that uses a common set of instructions from a meta-message set. The system ( 10 ) is generic, in that the system ( 10 ) is capable of connecting a processor ( 40 ) to any number of various peripheral devices ( 50 ), instead of being designed to interconnect a processor ( 40 ) only to a specific peripheral device ( 50 ). The system ( 10 ) interfaces between a standard non-true real time operating system and peripheral devices ( 50 ) in such a manner as to employ true real time peripheral device control using the meta-message set. The device controller of the system ( 10 ) allows a standard non-true real time operating system to send instructions from the meta-message set to implement true real time control of peripheral devices ( 50 ). The system ( 10 ) interfaces between a processor ( 40 ) and peripheral devices ( 50 ) such that the data and protocol communications interface of the system ( 10 ) allows the processor ( 40 ) to utilize a single protocol, associated data and set of instructions in order to communicate with peripheral devices ( 50 ) which are utilizing different protocols and associated data.
