Abstract: The present invention relates to a method and an apparatus for generating an executable file of a multi-instance service. The method includes: performing compilation for a source file corresponding to a multi-instance service, to obtain a first-class object file, where the multi-instance service includes N instances, and N is a natural number greater than or equal to 2; performing an object copy of the first-class object file N−1 times, to obtain N−1 new first-class object files; and performing linking to the first-class object file and the N−1 new first-class object files, to generate an executable file. In the present invention, an executable file is generated by performing mirroring and linking processing for an object file obtained by compilation, thereby reducing a development cost and a maintenance cost of software source code.
Abstract translation: 本发明涉及一种用于生成多实例服务的可执行文件的方法和装置。 该方法包括：对与多实例服务相对应的源文件执行编译，以获得第一类对象文件，其中多实例服务包含N个实例，N为大于或等于2的自然数; 执行第一类对象文件的对象副本N-1次，以获得N-1个新的一级对象文件; 并执行与第一类对象文件和N-1个新的第一类对象文件的链接，以生成可执行文件。 在本发明中，通过对通过编译获得的目标文件执行镜像和链接处理来生成可执行文件，从而降低了软件源代码的开发成本和维护成本。

Abstract: An electronic apparatus and a security protection method are disclosed. The electronic apparatus includes a security protection apparatus and a first processor. Security isolation exists between the security protection apparatus and the first processor. The first processor is configured to operate when driven by software, and the software includes an operating system and/or an application. The security protection apparatus is configured to: perform security detection on the software, and when detecting that the software is tampered with, perform a security protection operation on the electronic apparatus. In this way, the electronic apparatus may be monitored in real time during an operating process of the electronic apparatus, to avoid theft or modification of important data such as key data and improve security.

Abstract: A system on chip is integrated in a first semiconductor chip, and includes a secure element and at least one central processing unit that is coupled to the secure element. Security isolation exists between the secure element and the at least one central processing unit. The at least one central processing unit is configured to communicate with the secure element. The secure element includes a secure processor and a first memory that is coupled to the secure processor. The secure processor can suspend running first secure operating system software and further start second secure operating system software, to implement switching between multiple pieces of secure operating system software. Running data of running secure operating system software is stored in the first memory, and running data of secure operating system software that is not run is stored in a second memory outside the system on chip.

Abstract: Embodiments of the present invention disclose a network switching method, a version upgrade method, and a terminal device, which relate to the field of communications technologies. A terminal receives a user instruction that instructs the terminal to access a network of a target operator. If an operator of a network currently accessed by the terminal is different from the target operator, a preset file is read to obtain image information corresponding to the target operator. A target image file corresponding to the target operator is obtained according to the image information and version switching is performed according to the target image file. The preset file includes image information that corresponds to all image files of operators stored in the terminal in one-to-one correspondence.
