摘要:
The values of each possible component output R, G, and B may be pre-computed for all values of each possible component input Y, U, and V. Each contribution of Y, U, and V input may then be loaded into a register and added in parallel, without overflow, resulting in a computationally inexpensive RGB output from a YUV input. In one embodiment, contributions of Y, U, and V to each of R, G, and B are retrieved from pre-computed tables. The YUV contributions for each value of R, G, and B are packed into three data elements and added together in parallel, resulting in a value for an RGB output.
