    Abstract: This application provides a security control method and a computer system. A first domain and a second domain are deployed in the computer system, the second domain is more secure than the first domain, a program is deployed in the first domain, and a control flow management module and an audit module are deployed in the second domain. The second domain is more secure than the first domain. When the program in the first domain is executed, the control flow management module obtains control flow information by using a tracer. The audit module audits the to-be-audited information according to an audit rule, and when the to-be-audited information matches the audit rule, determines that the audit succeeds and then allows the first domain to perform a subsequent operation, for example, to access a secure program in the second domain.

    Abstract: This application provides a virtualized device, and an interrupt processing method running on the virtualized device. The method includes: performing, by a processor, the following operations in a guest mode: receiving, by the processor, an interrupt request from hardware; determining, by the processor, a processing entity of the received interrupt request based on a correspondence between the interrupt request and the processing entity; and when the processing entity of the received interrupt request includes the virtual processor currently running on the processor, determining, by the processor based on a correspondence between the interrupt request and an interrupt service routine, the interrupt service routine corresponding to the received interrupt request, and invoking the interrupt service routine to process the interrupt request. In this manner, trap-in and trap-out of a processor can be avoided for an application interrupt request, thereby reducing a processing delay of the application interrupt request.

    Abstract: Application discloses a picture encoding method and a terminal. In the method, a terminal divides the plurality of pictures into N groups, wherein the dividing is based on reference information of each of a plurality of pictures. The terminal encodes the N groups of pictures, where the following steps are performed on each one of the N groups of pictures: selecting a first picture from a target group according to a preset rule, and encoding the first picture, where the first picture is a picture first encoded in the target group, and the target group is any one of the N groups of pictures; selecting a reference picture for a second picture from the target group, where the second picture is a picture in the target group other than the first picture; and performing motion estimation on the second picture by using the reference picture, to encode the second picture.
