CFrame50
CFrame Compression Series

CFrame50 is the lossless&lossy frame buffer compression hardware IP designed by Chips&Media It is IP core that performs visually lossless compression of source image data from ISP or decoded data that are to be transferred to display chip so that efficient memory management, considerable bandwidth reduction and power saving can be all achieved.

CFrame50, the set of compression IP and decompression IP, has started to draw market attention its fast processing, various input formats, fully hardware configuration with a very small gate count.
