Abstract

Provided are a device, starting method thereof, and computer storage medium, the device comprising a central processing unit (CPU), an interface, and a double data rate (DDR) synchronous dynamic random access memory; the interface is configured to connect to a host device to acquire from the host device a system file capable of starting and operating a device, and transmit the system file to the DDR; the DDR is configured to store the system file; and the CPU is configured to operate a system via the system file stored in the DDR.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a device and a method for starting the device. Background technique [0002] With the rapid development of communication technology, the communication rate between devices is getting faster and faster, comparable to the access rate of permanent storage media such as disk and FLASH. Although the price of persistent storage media has been reduced, it is still a major component of the device cost. If the device does not contain persistent storage media, it cannot store system files and cannot be started. [0003] In view of the above problems, the present invention provides a device startup method. Using this startup method, the device does not need a permanent storage medium, which can reduce product costs. At the same time, serious failures caused by version corruption in the storage medium are also avoided. With this startup method, the software version can be updated in rea...
