Halftoning soft cores for low-cost digital displays

This paper presents hardware design of a family of soft cores that improve image quality on low cost digital displaying devices with limited color palette. The twoelement half-toning method proposed for gray-scale images [1] has been extended for color images. It also supports realtime video streams. Experimental results on Xilinx Spartan 3E1800 FPGAs show that frame rate for 512x512 video streams is more than 150fps.
