Abstract
An image display system comprises a processor 10, a main memory 20 and a display panel 30, where the main memory 20 includes an uncompressed image area 24 for storing image data relating to an image and a compressed image area 26 for storing compressed image data. The processor is microcode-programmed, and executes, after changes have been made in the uncompressed image area, a special sequence of microcode words in a micro program memory 12 of the processor for compressing at least those parts of the uncompressed image area that are subject to changes. The microcode-compressed parts of the image data are then stored in the compressed image area 26 of the main memory. Compressed image data may then be fetched from the compressed image area 26 and decompressed for enabling generation of an appropriate image signal. The generated image signal can finally be applied to the display 30 for refreshing the image.
