In Digital Communication, Digital Signal Processor (DSP) is an important block which performs several digital signal processing applications such as Convolution, Discrete Cosine Transform (DCT), Fourier Transform, and so on. Every digital signal processor contains MAC unit. The MAC unit performs multiplication and accumulation processes repeatedly in order to perform continuous and complex operations in digital signal processing. MAC unit also contains clock and reset in order to control its operation. Many researchers have been focusing on the design of advance MAC unit architectures for complex numbers so as to achieve minimum resource utilization and delay.
