Improved 64-Bit Binary Comparator

The comparison of two n-bit bit numbers is a critical operation for almost all digital systems. A comparator compares two n-bit values to determine which is greater, or if they are equal. In general it is used to compare two inputs. Comparison is the most fundamental operation in most of the modern digital systems. This paper presents an improved 64-bit binary comparator which employs pipeline architecture. This brief also adds a comparison between the existing 64 bit tree based binary comparator and the modified 64 bit binary comparator presented in this paper. Comparison between the modified and existing 64 bit comparators are done using VHDL followed by Modelsim 6.3f simulations.
