Abstract
Systems and methods for an efficient display data transfer algorithm over a network are disclosed. A compressed frame buffer update transmitted from a server via a network is received by a hardware decompression engine. The hardware decompression engine identifies one or more palette entries indicated in the compressed frame buffer update and determines whether the one or more palette entries is stored in a palette cache of the hardware decompression engine. If the one or more palette entries is not stored in the palette cache, the hardware decompression engine writes the one or more palette entries from an external palette memory to the palette cache. Decompressed display data is generated based on the compressed frame buffer update using the palette cache. The decompressed display data is written to an output buffer of the hardware decompression engine.
