ASIC implementation of a parallel binary comparator based on radix-2 tree structure, utilizing Carry Look Ahead (CLA) technique is proposed in this brief. This novel comparator architecture achieves both low power and high-speed operation, particularly at low-input data activity environments. The proposed comparator is designed using VHDL code and synthesized using ALTERA QUARTUS-II. Experimental evaluation of the proposed and state of-the-art designs revealed that the proposed comparator design exhibits a reduction in delay by 49.8% and gate count by 42.6% for a 16 bit design, compared to the best of the schemes used for comparison.
