Abstract
A system is used to determine if a sum of a first operand and a second operand is the same as a third operand wherein a comparison to the third operand is of variable length. This is particularly useful in a content addressable memory (CAM) where the likelihood of hit is commonly improved over a set associative cache and allows for the CAM to identify different things. For example, an entry can be one length to identify a page of a memory and another entry be a different length to identify a page of memory. This is better understood by reference to the following description and the drawings.
