VIRTUAL TO PHYSICAL MEMORY ADDRESS MAPPING WITHIN A SYSTEM HAVING A SECURE DOMAIN AND A NON-SECURE DOMAIN |
摘要 |
There is provided apparatus for processing data, said apparatus comprising: a processor operable in a plurality of modes and either a secure domain or a non-secure domain including: at least one secure mode being a mode in said secure domain; and at least one non-secure mode being a mode in said non-secure domain; wherein when said processor is executing a program in a secure mode said program has access to secure data which is not accessible when said processor is operating in a non-secure mode; said processor includes a non-secure translation table base address register operable in said non- secure domain to indicate a region of memory storing non-secure domain memory mapping data defining how virtual addresses are translated to physical addresses within said non-secure domain; and said processor includes a secure translation table base address register operable in said secure domain to indicate a region of memory storing secure domain memory mapping data defining how virtual addresses are translated to physical addresses within said secure domain. |
