Probabilistic arithmetic for JPEG image processing application

The purpose of my project is to investigate the use of probabilistic hardware (arithmetic approach in my project) in multimedia processing applications. To complete the project, first, I use full adders to constitute the ripple carry adders. Then these devices are used in jpeg encoding program and recording the results of peak signal-to-noise ratio (PSNR) and power consumption under different conditions. According to the probabilistic characteristics of the devices, I modified the algorithm of the ripple carry adders and multipliers, which will raise the peak signal-to-noise ratio and decrease power consumption efficiently. At last, I compare the results of deterministic encoding and probabilistic encoding and the modified probabilistic encoding results on image processing and get the conclusions.
