摘要: In a disclosed embodiment, data processing system comprises memory protection unit (MPU); and plurality of region descriptors associated with the MPU. Each descriptor is one multiple subsets includes an address range, settings, attributes for respective memory. The include data-only descriptors, instruction-only shared descriptors. are used to access regions instruction requests.
