APPARATUS AND METHOD FOR HIGH SPEED BOOTING IN DIGITAL IMAGE PROCESSING DEVICE

摘要

PURPOSE: A high speed booting method for a digital image processor is provided to reduce the load of a CPU by releasing the compassion of a compressed booting program through a lossless codec for image compression/release. CONSTITUTION: If a power source of a digital image processor is turned on, a CPU(Central Processing Unit) reads a compression booting program of a flash memory(210). The CPU commands the decompression of a read compression booting program to a compression/release process part(220). The compression-released booting program is stored in a RAM(230). The compression-released booting program is released by a lossless compression codec. The CPU boots the digital image processor through reading of the booting program of a RAM(240).
