METHOD AND APPARATUS TO SAVE AND RESTORE SYSTEM MEMORY MANAGEMENT UNIT (MMU) CONTEXTS |
摘要 |
<p>A wireless mobile device includes a graphic processing unit (GPU) that has a system memory management unit (MMU) for saving and restoring system MMU translation contexts. The system MMU is coupled to a memory and the GPU. The system MMU includes a set of hardware resources. The hardware resources may be context banks, with each of the context banks having a set of hardware registers. The system MMU also includes a hardware controller that is configured to restore a hardware resource associated with an access stream of content issued by an execution thread of the GPU. The associated hardware resource may be restored from the memory into a physical hardware resource when the hardware resource associated with the access stream of content is not stored within one of the hardware resources.</p> |
