Abstract
An apparatus having a plurality of first circuits, second circuits, third circuits and fourth circuits is disclosed. The first circuits may be configured to generate a plurality of first signals in response to (i) a priority signal and (ii) a request signal. The second circuits may be configured to generate a plurality of second signals in response to the first signals. The third circuits may be configured to generate a plurality of enable signals in response to the second signals. The fourth circuits may be configured to generate collectively an output signal in response to (i) the enable signals and (ii) the request signal. A combination of the first circuits, the second circuits, the third circuits and the fourth circuits generally establishes a programmable priority encoder. The second signals may be generated independent of the enable signals.
