In computing, an input–output memory management unit (IOMMU) is a memory management unit (MMU) connecting a direct-memory-access–capable (DMA-capable) I/O bus to the main memory. Like a traditional MMU, which translates CPU -visible virtual addresses to physical addresses , the IOMMU maps device-visible virtual addresses (also called device ...
Memory management (also dynamic memory management, dynamic storage allocation, or dynamic memory allocation) is a form of resource management applied to computer memory.The essential requirement of memory management is to provide ways to dynamically allocate portions of memory to programs at their request, and free it for reuse when no longer needed.
A 68451 MMU, which could be used with the Motorola 68010. A memory management unit (MMU), sometimes called paged memory management unit (PMMU), [1] is a computer hardware unit that examines all memory references on the memory bus, translating these requests, known as virtual memory addresses, into physical addresses in main memory.
Out of memory screen display on system running Debian 12 (Linux kernel 6.1.0-28) Out of memory (OOM) is an often undesired state of computer operation where no additional memory can be allocated for use by programs or the operating system. Such a system will be unable to load any additional programs, and since many programs may load additional ...
In operating systems, memory management is the function responsible for managing the computer's primary memory. [1]: 105–208 The memory management function keeps track of the status of each memory location, either allocated or free. It determines how memory is allocated among competing processes, deciding which gets memory, when they receive ...
Locations of the Gemini Guidance System. Project Gemini was the first with an on-board computer, as Project Mercury was controlled by computers on Earth. [5] The Gemini Guidance Computer was responsible for the following functions: [4] [3]
386 MAX (originally 386 to the Max, later Qualitas MAX) is a computer memory manager for DOS-based personal computers. [1] It competed with Quarterdeck's QEMM memory manager. It was manufactured by Qualitas. BlueMax was a special version designed for the IBM PS/2 with ROM compression to get the most of the Upper Memory Blocks.
