UPDATE METHOD FOR COMPRESSED SOFTWARE IMAGE AND AN APPARATUS PERFORMING THE SAME, CAPABLE OF UPGRADING A SOFTWARE IMAGE RECORDED IN A NONVOLATILE MEMORY IN A DIVIDED IMAGE UNIT

摘要

PURPOSE: An update method for compressed software image and an apparatus performing the same are provided to increase software storage capacity by minimizing a memory space when updating software image.;CONSTITUTION: An N number compression division image area and N+1 number compression division image area are read(S110). The compression state of the N number compression division image area is canceled from a second memory. A patch process is performed in the second memory(S120). The area where the patch process was performed is re-compressed. The re-compressed N number compression division image area is recorded in the N number compression division image area location of the first memory(S130). The re-compressed N number compression division image area is compared with the original N number compression division image area.;COPYRIGHT KIPO 2010
