Abstract:
1. An image data compression system for compressing a frame represented as a plurality of blocks, the image data compression system comprising: a lossless compression unit configured to receive the plurality of blocks and to perform lossless compression thereon resulting in a first code; a lossy compression unit configured to receive the plurality of blocks and to perform lossy compression thereon resulting in a second code; a code selection circuit configured to contemporaneously receive the first and second codes and configured to selectively output one of the first and second codes based upon an output size evaluated for at least one of the first and second codes; and a memory unit configured to receive at least one of the first and second codes output from the code selection circuit, the memory unit including a plurality of designated buffer spaces for storing compressed codes of the plurality of blocks, each designated buffer space corresponding to one of the plurality of blocks, wherein
