Each process running on a processor needs its own logical address space. This can only be realized if each process has its own page table. To support this, a processor that supports virtual memory must have a page table base register that is accessible by the operating system. For operating system security, this register is only accessible when the processor is in system mode. The operating system maintains information about each process in a process control block. The page table base address for the process is stored there. The operating system loads this address into the PTBR whenever a process is dispatched.
