These days complex numbers are represented in computer arithmetic using a divide-and-conquer technique wherein the real part of the number is represented by a separate base-2 binary string and the imaginary part of the number is represented by a separate base-2 binary string. Then each binary string is treated separately to evaluate the result of any operation on the given complex number. Complex Binary Number System (CBNS) is (-1+j)-based binary number system which allows both real and imaginary components of the complex number to be collectively represented as single binary string. In this paper, we have presented two designs of nibble-size complex binary multiplier circuits (decoder-based, minimum-delay) and implemented them on various Xilinx FPGAs.
