“…These changes result in improved image compression ratios. Deshmukh and Keote [22] designed a multiphase FIR filter using a bypass feed multiplier, add multiplier, and shift elements. They explained that the designs made using the bypass feed multiplier gave better results than the classical designs [22].…”

Polyphase filter banks (PFBs) are the most preferred multirate structures for subband coding in Digital Signal Processing (DSP) and communication. For PFB design, there are many important design parameters such as filter length and frequency selectivity. Also, to realize the desired frequency response in designs, stopband and passband attenuation are of considerable importance. In PFB design, researchers and practitioners frequently use iterative and meta-heuristic optimization methods. Heuristic techniques have a significant problem-solving ability in continuous and discrete solution space. Therefore, they give better results than other suggested methods, and their performance depends on the control parameters. In this study, Artificial Bee Colony (ABC) algorithm was employed for suggested design problem of PFB. In the first stage, the control parameters of the ABC algorithm were examined to improve the performance of the proposed PFB problem. In the second stage, the analysis was carried out by changing filter lengths (8-256) and filter band frequencies (0.3-0.7/0.4-0.6). All results obtained were also compared with the Particle Swarm Optimization algorithm (PSO) and the Genetic algorithm (GA). Finally, a DSP application of PFB was carried out according to best results achieved by the ABC algorithm for filter lengths and frequencies.

Abstract-An efficient direct form finite impulse response (FIR) Filter is designed to enhance the performance of digital filtering operation. Multiplication and Accumulation (MAC) units are important logic element in the FIR filter. In the conventional direct form FIR filters the number of logical elements count and delay is high for using Ripple carry adder (RCA) based MAC structure. Overcome this issue by proposed the reduced complexity SQRT Carry select adder (CSLA) based MAC unit for Direct form filter with reduced coefficient. The proposed filter takes less delay and less number of logical elements used by the filter. The designed filter is simulated and evaluated, using Modelsim 6.3c and Xilinx ISE simulation tool.
