摘要
The present invention relates to a method of implementing a programmable FIR filter, and more particularly, to a method and apparatus for improving the complexity of a shifter, or a cannonically signed digit (CSD) code for reducing the size of a shifter The coefficient h (n) of the possible filter is;(1), PK(The power of 2) { 0, 1, . , M-1} RTI ID = 0.0 SM, LIt is possible to realize a shifter which is simplified by about 25% to 33% when the coefficient is expressed by the same coefficient as that of the conventional method, and it is possible to reduce the shifter by more than 50% This is an implementation method of an FIR filter that does not require a multiplier with a power of 2 that can replace a partial multiplier with a shifter and an adder.
