Abstract:
Methods and systems for pre-fetching address translations in a memory management unit (MMU) of a device are disclosed. In an embodiment, the MMU receives a pre-fetch command from an upstream component of the device, the pre-fetch command including an address of an instruction, pre-fetches a translation of the instruction from a translation table in a memory of the device, and stores the translation of the instruction in a translation cache associated with the MMU.
