Hardware support for virtual memory As covered in the section called “The TLB” , the processor hardware provides a lookup-table that links virtual addresses to physical addresses. Each processor architecture defines different ways to manage the TLB with various advantages and disadvantages.

Virtual memory, on the other hand, allows the program to specify any address and the operating system and hardware do the hard work of translating to a physical address. The TLB The Translation Lookaside Buffer (or TLB for short) is the main component of the processor responsible for virtual-memory.

Hardware support for virtual memory, then, consists of specialized hardware for this purpose. This is what’s normally called a memory management unit, which implements a translation lookaside buffer in hardware. In this way, the CPU can efficiently access remapped memory, without having to make additional access(es) to main memory in order to access the TLB.

The hardware necessary to support virtual memory is the same as for paging and swapping: A page table and secondary memory. ( Swap space, whose allocation is discussed in chapter 12. A crucial part of the process is that the instruction must be restarted from scratch once the desired page has been made available in memory.

Jul 25, 2011 · A rule of thumb for virtual memory is 1.5 times the amount of physical RAM you have. 6GB is good if you have 4GB of RAM. 9GB is good if you have 6GB or RAM, etc.
https://en.wikipedia.org/wiki/Virtual_memory
Virtual memory is an integral part of a modern computer architecture; implementations usually require hardware support, typically in the form of a memory management unit built into the CPU. While not necessary, emulators and virtual machines can employ hardware support to increase performance of their virtual memory implementations. [3]
