Complex number multiplication is an important arithmetic function in digital communication, radar, and optical system. Many major functions in the communication systems such as channel equalization; modulation and demodulation all deal with data streams and coefficients represented by complex numbers. Therefore efficient implementation of multiplier circuit for complex numbers is of significant...

Financial and commercial data are mostly represented in decimal format. To avoid errors introduced when converting some fractions to binary, these processed with arithmetic. Most processors only have hardwired binary arithmetic units. So, operations executed slow software-based functions. For the fast execution of operations, dedicated hardware units been proposed designed FPGA. Decimal multipl...
