In hardware systems where a multitude of sense lines must be tracked dependent on the changing state of the environment, it is important that critical sense lines be responded to quickly when activated. A typical scheme for doing this would be to divide the sense lines into groups, compare the lines per group with mask bits to activate an interrupt, and funnel a single interrupt line per group to an intelligent controller. The scheme described here expands on this idea and improves its availability and reliability.
