Claims
- 1. A data instrumentation system comprising:
- a) a plurality of trace boards having a plurality of state machines for asynchronously generating a plurality of control signal sets, each of said plurality of control signal sets having two control signals;
- b) a plurality of detection circuits coupled to said state machines for receiving said plurality of control signal sets, detecting active control signals in said received plurality of control signal sets, and generating a plurality of detection signal sets, each of said plurality of detection signal sets having two detection signals corresponding to the two control signals of one of said plurality of control signal sets, each of said plurality of detection signal sets being used for identifying active control signals being detected in the corresponding control signal set; and
- c) a resolution circuit coupled to said detection circuits and said state machines for receiving said plurality of detection signal sets, and generating an output signal having two possible output states, said output signal being generated based on a current state of said output signal and selected ones of said received detection signals that are applicable to the current state of said output signal.
- 2. The data instrumentation system as set forth in claim 1, wherein,
- said detection circuits further receive a common feedback signal set from said resolution circuit, said common feedback signal set having two feedback signals, one feedback signal for each control signal in a control signal set;
- said detection circuits further base said generation of said plurality of detection signal sets on said common feedback signal set.
