Development of a High Speed Digital Complex Multiply-adder
Yongbo Zhao · 2004
Complex multiply-adder is one of the operations often used in real time digital signal processing systems, with the development of real time signal processing, the demand for the speed of operation is increasing. This paper develops a high speed complex multiply_adder circuit by using complex programmable logic devices (CPLD). In this complex multiply_adder add times can be controlled by an input signal and the circuit can also output its conjugation at the same time. This design has low cost and easy program, which can be widely used in digital signal processing systems according to different requirements.
