21st Century Slide Rules with Logarithmic Arithmetic
Design How-To 2/6/2002 Post a comment
Using the Logarithmic Number System (LNS) as an alternative to fixed- and floating-point arithmetic reduces multiplication, division, and square root implementation while improving power and area. Mark G. Arnold of the University of Manchester discusses three forms of LNS along with a Verilog implementation of a linear-Lagrange interpolator targeted for an FPGA.
FPGA-Based FIR Filters using Distributed Arithmetic
Design How-To 2/4/2002 Post a comment
You employ Distributed Arithmetic techniques to save resources in multiply-and-accumulate (MAC) structures implementing DSP functions. M. Martinez-Peiro and fellow authors from the Universidad Politecnica de Valencia, Spain, describe three types of FPGA-based FIR filters they designed using DA methodology, along with a comparison of filter performance.
