Abstract :
The vital role of complex numbers in various electrical and computer engineering applications demands formulation of an efficient method for their representation and processing in the central processing unit of a microprocessor. Complex Binary Number System (CBNS) allows both real and imaginary parts of a complex number to be represented as a single unit (instead of two separate units as in today´s microprocessors), thus allowing for faster arithmetic operations of complex numbers and increase in overall system performance. In this paper, an introduction to CBNS has been presented and various algorithms for its arithmetic operations have been outlined. Information about adder, subtract or, multiplier, and divider circuits for CBNS has been provided and avenues of future research in this arena have been identified.
