As modern user interfaces become ever more graphics intensive, the demands on graphics memory to hold the textures increase. This is particularly relevant for embedded systems, where resources come at a higher premium, and can be a challenge for system performance. One of the key remedies for this is to reduce the memory requirements of the […]
