1. For use with a fast pattern processor having an internal function bus, an external device transmission system, comprising: a context memory subsystem configured to maintain a plurality of argument signature registers, each of said plurality of argument signature registers being associated with a corresponding context and containing a corresponding argument; a pattern processing engine configured to dynamically modify an argument and generate a transmit command as a function of a context associated with said modified argument; and an output interface subsystem configured to receive said transmit command, and transmit said modified argument based upon said transmit command to an external device.
