Jan 15, 2025 · Virtual memory is a memory management technique used by operating systems to give the appearance of a large, continuous block of memory to applications, even if the physical memory (RAM) is limited. It allows larger applications to run on systems with less RAM.

What is Virtual Memory - Learn about virtual memory in computer organization architecture or coa, advantages of virtual memory, configuration of virtual memory, logical and physical address space with proper diagram

In this chapter, we are going to learn about virtual memory in detail that includes its design factors, the concepts of segmentation and paging, address translation activities, translation look-aside buffer (TLB) and its advantages.

Virtual memory, apart from overcoming the main memory size limitation, allows sharing of main memory among processes. Thus, the virtual memory model provides decoupling of addresses used by the program (virtual) and the memory addresses (physical).

Learn how virtual memory works with a detailed diagram, explaining memory management techniques, page tables, and the relationship between physical and virtual memory.

There are three architectural parameters that characterize a virtual memory system and hence the architecture of the MMU. P is the number of address bits used for the page offset in both virtual and physical addresses. V is the number of address bits used for the virtual page number.

RISC-V defines three different virtual memory specifications o Sv32: Two level hierarchy, 32-bit virtual, 34-bit physical address o Sv39: Three level, 39-bit virtual, 56-bit physical address

A diagram of virtual memory typically illustrates the relationship between the virtual memory, physical memory, and secondary storage. It shows how the virtual address space of a program is divided into pages, which are then mapped to different locations in physical memory or …

Virtual Memory Summary Virtual memory provides • Protection and sharing • Illusion of large main memory • Speed/Caching (when viewed from disk perspective) • Virtual Memory requires twice as many memory accesses, so cache page table entries in the TLB. • Three things can go wrong on a memory access • TLB miss
