Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0019] see figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the method for accelerating the startup speed of the embedded system in the present invention. Such as figure 1 As shown, the method includes the following steps:

[0020] S101: judging whether an external memory exists when the embedded system starts.

[0021] Among them, the embedded system is a special-purpose computer system based on computer technology, application-centric, and software and hardware can be tailored. The external storage may be at least one of U disk, SD card, mobile hard disk, memory stick, microdrive, compact flash memory and media card, or other types of storage. The process of judging whether there is an external memory may be a process in which the system identifies whether the external memory is successful after the external memory is ...

Abstract

The invention discloses a method for increasing a starting speed of an embedded system and the embedded system thereof, and relates to the technical field of computers. The method for increasing the starting speed of the embedded system comprises: judging whether an external memory exists or not when the embedded system starts to be started; and when it is judged that the external memory exists, loading the starting mirror image file stored in the main memory and the starting mirror image file stored in the external memory into the memory in parallel, wherein the starting mirror image file loaded into the memory from the main memory is different from the starting mirror image file loaded into the memory from the external memory. Through the above method, the available external memory is fully utilized, the starting mirror image files are stored in the external memory, and the starting mirror image files stored in the main memory and the external memory respectively are loaded into thememory at the same time in the system starting stage, so that the time consumed for loading all the starting mirror image files is shortened, the bandwidth for loading the starting mirror image filesis widened, and the starting speed of the embedded system is increased.

Description

technical field [0001] The invention relates to the related field of computer technology, in particular to a method for accelerating the start-up speed of an embedded system and the embedded system thereof. Background technique [0002] With the development of informatization, intelligence, and networking, embedded systems have also gained broader development space. At present, the general embedded system places the boot image file in the main memory. During system startup, all boot image files stored in the main memory must be loaded into the memory. However, the loading process of this section generally takes a long time, thereby slowing down the startup speed of the embedded system. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a method for accelerating the start-up speed of the embedded system and the embedded system thereof, which can shorten the time spent loading the start-up image file into the memor...
