ABSTRACT:
A processor is provided that includes a primary memory and color conversion logic. The primary memory may store a first color look-up table (LUT) related to a second color space. The color conversion logic, in response to a received set of pixels having color values in a first color space, converts the received set of pixels to a second color space. The color conversion logic selectively accesses, based on a comparison of one or more pixel parameters to a threshold, one of the primary memory and a secondary memory located on a second device to obtain a color value of the second color space that is associated with each pixel of the set of pixels. The color conversion logic monitors the number of times that each of the primary memory and the secondary memory are accessed and automatically adjusts the threshold to maintain an access ratio.
