Key Terminologies of MMU
Few key terms are mentioned below:
- Virtual Address: The address generated by the CPU during program execution, representing a location in the virtual address space.
- Physical Address: The physical memory address of a virtual address on a computer, as determined by address translation performed by the MMU.
- Memory Paging: It is a technique used to manage memory which allows a computer to share its memory resources by storing some portion of process on disk or other secondary memory.
- Address Translation: The method by which the MMU converts virtual addresses into physical addresses so that the CPU can access the appropriate places in the computer’s memory.
- Cache Memory: It is a high speed and Quick-access data storage layer, small-sized memory that speeds up CPU operations by storing frequently used data or instructions for fast processing. MMUs may interact with the cache to optimize memory access.
What is Memory Management Unit(MMU)?
A Memory Management Unit (MMU) is a very important type of internal hardware. It is used for high efficiency and secure utilization of a computer’s memory devices. Another name for it is a paged memory management unit (PMMU). The main purpose of an MMU is to serve as a link or bridge between the physical memory of the computer and the central processing unit (CPU).
It is important for the smooth operation of programs and effective management of data. Let us explore about MMUs in more detail in this article. This article will define an MMU, and cover some key terminologies. Finally, we’ll finish up the article with some information on the Importance of MMUs, and frequently asked questions along with its diagrams and more.
