Memory Management Units (MMU)

A Memory Management Unit (MMU) is a hardware component that manages the translation of virtual memory addresses to physical memory addresses. The MMU is an essential component of modern computer systems and is responsible for providing a layer of abstraction between the operating system and the physical memory of the system.

The MMU translates virtual memory addresses to physical memory addresses using a page table, which is a data structure that maps virtual memory addresses to physical memory addresses. The page table is stored in memory and is managed by the operating system. When a program requests data from memory, the MMU uses the page table to translate the virtual memory address to a physical memory address.

The MMU also provides memory protection by assigning different access permissions to different memory regions. This allows the operating system to isolate programs from each other and prevent unauthorized access to memory. For example, the MMU can assign read-only access to certain memory regions to prevent programs from modifying critical data.

Another important function of the MMU is memory sharing. The MMU allows multiple programs to share memory regions, which can improve system performance and reduce memory usage. By sharing memory, programs can communicate with each other more efficiently and reduce the need for redundant data storage.
