Additional memory may be allocated and/or deallocated at this time. Thus, the virtual address 0x0012F980 has a byte index of 0x980. CS350 Operating Systems Spring 2014 The logical address generated by the CPU is first checked by the limit register, If the value of the logical address generated is less than the value of the limit register, the base address stored in the relocation register is added to the logical address to get the physical address of the memory location.If the logical address value is greater than the limit register, then the CPU traps to the OS, and the OS terminates the program by giving fatal error.
