1. A data-analyzing unit for monitoring and/or analyzing events on an information bus, the data-analyzing unit including an event recognition unit comprising: at least one comparator coupled to the information bus, each said comparator configured to produce an output in response to a determined event on said information bus; a sequencer state machine coupled to said at least one comparator; and including a memory and a register, said register having one or more outputs coupled back to one or more inputs to said memory for enabling recording in said memory of a history of state outputs from said sequencer state machine, said sequencer state machine responsive to said history of state outputs and outputs from said at least one comparator for determining sequential dependencies of events, whereby a state output of the sequencer state machine is dependent on a historical sequence of information provided thereto.
