In this paper, a modified finite impulse response (FIR) filter design has been proposed for the denoising bio-electrical signals like Electrooculography(EOG). The proposed filter architecture uses modified multiplier block, which is implemented using modified Radix-2r arithmetic-based representation for minimizing the multiple constant multiplication and conventional ripple carry adders are replaced with 4:2 compressors. This proposed architecture is implemented by using Radix-2r-based multiplier and 4:2 compressor architectures for achieving better improvement in the critical path delay. The Radix-2r-based arithmetic bit recording is used in order to reduce the design complexity of the multiplication. The proposed architecture significantly reduced the delay when compared to existing and conventional architectures.

使用 Radix-2r 乘法器的高速 FIR 滤波器及其在 EOG 信号去噪中的应用

在本文中,针对眼电图(EOG)等生物电信号的去噪,提出了一种改进的有限脉冲响应(FIR)滤波器设计。所提出的滤波器架构使用修改后的乘法器块,它是使用修改后的 Radix-2r用于最小化多个常数乘法和传统纹波进位加法器的基于算术的表示被替换为42压缩机。这个提议的架构是通过使用 Radix-2r-基于乘数和42用于更好地改善关键路径延迟的压缩器架构。基数-2r使用基于算术位的记录以降低乘法的设计复杂性。与现有的和传统的架构相比,所提出的架构显着减少了延迟。
