摘要： The present application relates to a mechanism for managing access to at least one shared integrated peripheral of a processing unit and a method of operating thereof. The mechanism is operative in an available state and a locked state. The mechanism comprises at least one context register and a bus interface for receiving a request. A filtering unit obtains information relating to a context of the received request. If in the available state, a managing unit loads the context register with the obtained context information; and grants access in response to the received request. If in the locked state, the managing unit detects whether the obtained context information matches with the context information stored in the context register; and if the obtained and stored context information match, grants access in response to the received request. Otherwise, access is denied.
摘要翻译：本申请涉及用于管理对处理单元的至少一个共享集成外围设备的访问的机制及其操作方法。该机构在可用状态和锁定状态下工作。该机制包括至少一个上下文寄存器和用于接收请求的总线接口。滤波单元获得与接收到的请求的上下文有关的信息。如果处于可用状态，则管理单元使用获得的上下文信息加载上下文寄存器; 并根据收到的请求授予访问权限。如果处于锁定状态，则管理单元检测所获取的上下文信息是否与存储在上下文寄存器中的上下文信息匹配; 并且如果所获得和存储的上下文信息匹配，则响应于接收到的请求来授予访问权限。否则访问被拒绝。

摘要： A system-on-chip device comprises a core supporting a first virtual machine image and a virtual machine monitoring unit capable of communicating with the first virtual machine image. A shareable resource is also provided as well as a conflict detection unit capable of communicating with the virtual machine monitoring unit and the first virtual machine image. The conflict detection unit is arranged to detect, when in use, an access conflict caused by more than one virtual machine image attempting to access initially the shareable resource. The conflict detection unit is arranged to refer, when in use, the access conflict in response to detection thereof to the virtual machine monitoring unit for resolving of the access conflict, thereby handling the access conflict before the virtual machine monitoring unit.

摘要： A 3D graphics system uses encryption keys to decrypt received and stored texture tiles of a texture in accordance with received and stored texture tile status data which indicates whether a texture tiles is encrypted or not and which one of the encryption keys is used. The decrypted texture tiles are rendered and at least a plurality of the rendered tiles is encrypted. The encrypted rendered tiles are stored in a frame buffer. Buffer tile status data is stored which indicates whether a rendered tile is encrypted or not before storage in the frame buffer, and which one of the encryption keys has been used. The encrypted rendered tiles stored in the frame buffer are decrypted in accordance with the buffer tile status data.
