A memory management unit is configured to receive memory access requests and to translate a virtual address included in a memory access request from a requesting master device into a physical address indicating a storage location in memory. The memory management unit has an internal storage unit ...

A memory management unit (MMU) is a computerhardwarecomponent that handles allmemoryand caching operations associated with the processor. In other words, the MMU is responsible for all aspects ofmemory management. It's usually integrated into the processor, although, in some systems, it occupies a...
How to speed MMU (Memory Management Unit) is a key to improve the performance of microprocessor. In this paper, we propose a new architecture of MMU. This architecture is composed of adder, cache, temporary register, segment test circuit and address latc...

内存管理单元(MMU)的一个重要功能是使系统能够运行多个任务,作为独立的程序在它们自己的私有虚拟内存空间中运行。他们不需要了解系统的物理内存映射(即硬件实际使用的地址),也不需要了解可能同时执行的其他程序。 您可以为每个程序使用相同的虚拟内存地址空间。您还可以使用连续的虚拟内存映射,即使物理内存是碎片化不连续的...
