Graphic rendering system capable of performing real-time compression and decompression

A graphic rendering system capable of performing real-time compression and decompression, comprising:

• a storage device, for storing one or more compressed sprite images and one or more compressed background images;
• a decompressor, connected to the storage device, for performing a decompression operation on the one or more compressed sprite images and background images to thereby obtain one or more sprite images and background images respectively;
• a rendering engine, connected to the decompressor, for performing an image processing on the one or more sprite images and background images to thereby produce a partial display image;
• a first real-time compressor, connected to the rendering engine, for performing a real-time compression processing on the partial display image to thereby produce a compressed partial display image;
• a frame buffer, connected to the first real-time compressor, for temporarily storing the compressed partial display image;
• and
• a first real-time decompressor, connected to the frame buffer, for performing said real-time decompression processing on the compressed partial display image to thereby output an image signal for display.
