Filed: 2017-05-05
Abstract: A data processing device manages access permissions, known as capabilities, for pointers 66. Such permissions include the address range 64 the pointer is permitted to access and access rights 66. The program counter 82 has optional access permissions 84, 86, which may be enabled for different privilege levels according to a configuration store 76. When changing privilege level form a source level to a destination level in response to an exception, the device determines from the register if the source level is using permissions for the program counter. If so the program counter is saved with its permissions. Otherwise, only the value is saved. It then determines from the register if the destination level is using access permissions for the program counter. If so, the appropriate permissions are set. If not, the permissions are disabled. On returning from the exception, the permissions are restored if permissions for the original source level permissions are enabled in the register. Otherwise, the permissions are disabled.
