Registerless Multiplierless YCoCg-R and YCoCg Color Space Converters Hardware Implementation
Multimedia data, e.g., images and videos, are widely used over the internet and on computers. Image processing applications require color space conversion to be able to deal with these types of data more efficiently. This paper investigates three color space conversions and proposes simplified combinational hardware designs and FPGA realizations for RGB to YCoCg-R and YCoCg color spaces encoders and decoders and compares them to their sequential counterparts. The proposed hardware design for the encoders and decoders uses only adders and subtractors without any registers or multipliers. The proposed YCoCg-R converter exhibits better resources utilization com pared to implementing the design using shift registers, where it uses 56.3% and 72.1% less LUTs and FFs, respectively. Similarly for the YCoCg color space, the combinational design used 48.1% less LUTs and 67.8% less FFs than its sequential counterpart
