    摘要: A booting system is disclosed for booting from a non-XIP memory utilizing a boot engine that does not have ECC capabilities during booting. The booting system includes: a non-XIP memory for storing a boot loader code and a plurality of operation system (OS) images, wherein the OS images in the non-XIP memory correspond to a same source image; an XIP memory for storing a shadowed boot loader code and OS images; a Central Processing Unit (CPU) for executing the OS images stored in the XIP memory; a code shadowing module for performing error detection checking on the OS images in the non-XIP memory and shadowing the boot loader code and OS images to the XIP memory; and a non-XIP interface for enabling the boot engine to access the non-XIP memory.
