Web21 Virtual-To-Physical Lookups Programs only know virtual addresses Each program or process starts from 0 to high address Each virtual address must be translated May involve walking through the hierarchical page table Since the page table stored in memory, a program memory access may requires several actual memory accesses Watch queue depth and IOPS. 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. Suppose we have 28 bit virtual address space and 32 bit physical address space. Every step that you skip in this process increases the likelihood that your conversion wont work.

Set the process context to the desired process: Use the !pte extension with the virtual address as its argument. This will allow users to gain insight into where precisely a program spends time and contribute to solving time-sensitive issues. Memory Allocation Techniques:To store the data and to manage the processes, we need a large-sized memory and, at the same time, we need to access the data as fast as possible. Although the virtual addresses are the same, the OS handles the physical addresses, which are completely different. Sysprep is a little different across the various iterations but the unifying goal is to generalize the installation for a new install and then shut the virtual machine down.
