Abstract: This disclosure proposes techniques for graphics processing. In one example, a graphics processing unit (GPU) is configured to access a memory according to one of an unsecure mode and a secure mode. The GPU may include a memory access controller configured to direct memory transactions from at least one hardware unit of the GPU to an unsecure memory unit or a secure memory unit based on the unsecure mode or secure mode and a resource descriptor associated with a memory resource.

In one example, a graphics processing unit (GPU) is configured to access a memory according to one of an unsecure mode and a secure mode. The GPU may include a memory access controller configured to direct memory transactions from at least one hardware unit of the GPU to a secure context bank in a memory controller when the GPU is operating in a secure mode, and configured to direct memory transactions from the at least one hardware unit of the GPU to an unsecure context bank in the memory controller when the GPU is operating in the unsecure mode.
