There are two different types of compression used on the Embedded Linux Platform that the present invention is targeting. For the kernel, a singular compression is used. A whole kernel is compressed into a single compressed zImage by zlib at once. When the kernel is loaded into RAM, the whole kernel has to be decompressed to RAM and executes there. The root file system is built through the CramFS that employs a different compression mechanism. It is a block-based compression. When the device is running, it is not necessary to load the whole file system to RAM. The kernel mounts the file system and performs the decompression on a file when it is needed.
