On the Comparison of Different Number Systems in the Implementation of Complex FIR Filters
نویسندگان
چکیده
The aim of this work is to compare in terms of performance, area and power dissipation, the implementations of complex FIR filters based on the following number representations: traditional two’s complement (TCS), Quadratic Residue Number System (QRNS) and radix-2j Redundant Complex Number Systems (RCNS)). The resulting implementations, designed to work at the same clock rate, show that filters implemented in QRNS outperforms in terms of area and power dissipation the filters implemented in TCS and RCNS.

FPGA vs GPU Performance Comparison on the Implementation of FIR Filters
FIR filters find place in digital signal processing applications that require stopping a frequency band while passing another band or removing noise. Due to the complex structure and parallelism property of FIR filters, dedicated reconfigurable hardware are preferred for implementation rather than CPUs. Recently, GPGPU emerged as an effective technique for solving computation-intensive problems...

Tracking filters are extensively used within object tracking systems in order to provide consecutive smooth estimations of position and velocity of the object with minimum error. Namely, Kalman filter and its numerous variants are widely known as simple yet effective linear tracking filters in many diverse applications. In this paper, an effective method is proposed for designing and implementa...

Software system verification is an efficient technique for ensuring the correctness of a software product, especially in safety-critical systems in which a small bug may have disastrous consequences. The goal of software verification is to ensure that the product fulfills the requirements. Studies show that the cost of finding and fixing errors in design time is less than finding and fixing the...
