Abstract

The invention provides a trusted execution environment construction method and system for a graphics processor, and the method comprises the steps: S1, building control information according to a GPUtrusted execution environment, building a GPU trusted execution environment, and obtaining the building control information of the GPU trusted execution environment; S2, according to the GPU submission control information and the GPU execution task control information, carrying out GPU submission and task execution to acquire GPU submission and task execution result information; checking and starting a GPU task in a trusted execution environment according to the GPU checking control information and the GPU starting control information to acquire GPU submission and execution task result information; and S3, obtaining trusted execution environment construction result information oriented to the graphics processor. Different PASIDs are allocated to different GPU processes by utilizing the virtualization support of IOMMU, so that the memory isolation between the trusted execution environments of each GPU is realized.

Description

technical field [0001] The present invention relates to the technical field of graphics processors, in particular to a method and system for building a trusted execution environment for graphics processors. Background technique [0002] The concept of artificial intelligence appeared in the middle and late last century. Restricted by the limited computing power of computers at that time, as well as the lack of empirical samples and data, related technologies were difficult to realize at that time. After entering the 21st century, several problems that limit the development of artificial intelligence have been solved one after another. First, the computing power of the CPU continues to increase following Moore's Law, and the emergence of cloud computing has further reduced the cost of using computing power; second, empirical samples and data are abundant and easy to obtain. Finally, the introduction of deep learning neural network algorithms and the use of graphics processo...
