Abstract:
A finite impulse response (FIR) filter circuit design method using approximate computing, the FIR filter circuit design method including: replacing adders of the FIR filter with approximate adders; and performing a synthesis work according to a set approximate synthesis flow when the replacing of the adders of the FIR filter are replaced with the approximate adders is performed, wherein, in the approximate synthesis flow, a numeric column of each of the approximate adders is divided into an accurate part and an inaccurate part, and a numeric column of the inaccurate part is approximated. In the FIR filter, conventional adders/subtractors are replaced with addition/subtraction having an automated synthesis flow so that energy consumption can be reduced.

Claim (Index 7):
The FIR filter circuit design method of  claim 1 , wherein, in the approximate synthesis flow, to verify the output quality of a processed image, peak signal-to-noise-ratio (PSNR) is defined by Equation 3: PSNR = 10 \u00d7 log \ue8a0 ( 255 2 \u03c3 noise 2 ) , ( 3 ) where \u03c3 noise 2  is a variance of a difference.
