Abstract :
Commonality of various algorithms is analyzed based on the research of algorithms commonly used digital signal processing and a reconfigurable cell is proposed. A reconfigurable system with the cells is designed, which is widely used in a variety of digital signal processing. The principle and method of using this system are discussed with the basic algorithms of digital signal processing - multiplication and adder - as example. By means of simulation and implementation, it is found that this system has much higher processing speed and efficiency, compared with other kinds of GM multipliers.
