Abstract
An unsigned integer comparator for use when comparing an n-bit received signal (such as an address) with an n-bit known signal ("comparison address"). The first stage of the comparator may be configured in advance, since the values of both a "comparison signal" and a "select signal" are known a priori. When the "current signal" arrives, the bits of this signal are then compared against the associated bits of the comparison signal. Subsequent stages of the comparator perform comparison operations of increasing length, dependent upon the outcome of the previous stage (i.e., a first set of 2-bit comparisons, then 4-bit, 8-bit, etc.), until the entire n-bit integers are ultimately compared and a final output is generated.
