Multiplication and Accumulation (MAC) unit of Finite Impulse Response (FIR) filter has been designed using efficient multiplier and adder circuits for optimized APT (Area,Power and Timing) product. In this paper, the design of direct form FIR filter with efficient MAC unit has been presented. Initially, full adder and half adder structures are shrunk down by reducing number of gates. These compact full adder and half adder structures are incorporated into Wallace Multiplier and Improved Carry-Save Adder. The proposed 16-bit Carry-Save Adder has been improved by splitting into four parallel phases. Consequently the delay of enhanced Carry- Save Adder is reduced. Generation of carry output is performed using number of OR gates in a sequential manner. All these enhanced architectures are incorporated into the Digital FIR Filter to reduce the area, delay and power utilization.展开更多

On the basis of previous studies on face theory and face saving strategy, this research analyzes the problems of face in Chinese and western communication, the differences of face views and values between them and discusses the strategies to save face of the Chinese and westerners as well as during Chinese and western cross-cultural communication, reducing the cultural conflicts resulted from face and improving cross-cultural communication.展开更多
