1. An integrated circuit, comprising: a lookup engine that reads a first result value and a first indicator from a memory and determines if the first result value is a final result value, wherein the lookup engine outputs the first result value when the first indicator indicates that the first result value is the final result value, and wherein the lookup engine does not output the first result value and reads a second result value and a second indicator from the memory when the first indicator indicates that the first result value is not the final result value.
