Review of Architectures for Low Power and Reconfigurable FIR Filters
نویسندگان
چکیده
Reconfigurability, low complexity and low power consumption are the key requirements in a FIR filter. Many works have been done on the reduction of area and power requirements but Reconfigurability is less addressed in the papers. In this paper, a survey has been conducted on the works done in the past on the Reconfigurability of the FIR filters and various algorithms being used for making the FIR filters less complex. Keywords—Canonical signed digit (CSD), CSHM, finite-impulse response (FIR) digital filters, Reconfigurability, subexpression elimination.

متن کاملA Tutorial on Multiplierless Design of FIR Filters: Algorithms and Architectures
Finite impulse response (FIR) filtering is a ubiquitous operation in digital signal processing systems and is generally implemented in full custom circuits due to high-speed and low-power design requirements. The complexity of an FIR filter is dominated by the multiplication of a large number of filter coefficients by the filter input or its time-shifted versions. Over the years, many high-leve...
