Abstract
A number of detection circuits, one for each source of control signal set inputs, and a high speed resolution circuit, are provided for resolving multiple control signal inputs into a single stable, predictable, and useful output signal. The detection circuits detect active control signals in the various control signal set inputs, and generate detected signals. The high speed state resolution circuit generates an output signal, conditionally changing the output state based on the detected signals and the current state being output. When deciding whether to change the output state, the high speed resolution circuit considers only the detected signals applicable to the current output state and responds accordingly, ignoring all other detected signals that are not applicable. The detection circuits and the resolution circuit are coordinated in timings, ensuring proper resolution.
