【 摘 要 】

High power problem become one of the most important bottleneck of the IC industry. FIR filter is a most basic element in a digital signal processing system. In this paper, we managed to design a new FIR filter that can have low power. We use a residue number system to design a FIR filter in order to reduce power. In our model, we designed a serial modulus adder and a new way to compute modulus bit by bit. We use a way of looking up table in place of multiplication. By experiment verification, these methods in each module can effectively cut down the power and area.
