Title: | Complexity reduction of high-speed FIR filters using micro-genetic algorithm | Authors: | Cen, L. Lian, Y. |
Issue Date: | 2004 | Citation: | Cen, L.,Lian, Y. (2004). Complexity reduction of high-speed FIR filters using micro-genetic algorithm. International Symposium on Control, Communications and Signal Processing, ISCCSP : 419-422. ScholarBank@NUS Repository. | Abstract: | In the ASIC implementation, a long FIR filter can operate at high speed without pipelining if it is factorized into several short filters whose coefficients are in the form of the sum of signed powers-of-two terms. Such implementation reduces the hardware cost and lowers the power consumption significantly as it requires no multipliers. This paper presents a filter synthesis method that factorizes a long filter into several short filters and quantizes the coefficients of all short filters into signed powers-of-two values simultaneously using micro-genetic algorithm (μGA). The proposed μGA speeds up the optimization process greatly compared to conventional GA. | Source Title: | International Symposium on Control, Communications and Signal Processing, ISCCSP | URI: | http://scholarbank.nus.edu.sg/handle/10635/69667 | ISBN: | 0780383796 |
