Abstract :
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 two-element half-toning method proposed for gray-scale images has been extended for color images. It also supports real-time video streams. Experimental results on Xilinx Spartan 3E1800 FPGAs show that frame rate for 512 times 512 video streams is more than 150 fps.
