  2. Input–output memory management unit - Wikipedia

    en.wikipedia.org/wiki/Input–output_memory...

    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 ...

    The vast majority of Intel server chips of the Xeon E3, Xeon E5, and Xeon E7 product lines support VT-d. The first—and least powerful—Xeon to support VT-d was the E5502 launched Q1'09 with two cores at 1.86 GHz on a 45 nm process. [2]

  4. Memory protection unit - Wikipedia

    en.wikipedia.org/wiki/Memory_protection_unit

    A memory protection unit (MPU) is a computer hardware unit that provides memory protection.It is usually implemented as part of the central processing unit (CPU). [1] MPU is a trimmed down version of memory management unit (MMU) providing only memory protection support.

    IOMMU hardware-based GPU isolation support, increasing security by restricting GPU access to system memory. GPU paravirtualization support, enabling display drivers to provide rendering capabilities to Hyper-V virtualized environments. Brightness, a new interface to support multiple displays that can be set to calibrated nit-based brightness ...

  6. Memory-mapped I/O and port-mapped I/O - Wikipedia

    en.wikipedia.org/wiki/Memory-mapped_I/O_and_port...

    Memory-mapped I/O is preferred in IA-32 and x86-64 based architectures because the instructions that perform port-based I/O are limited to one register: EAX, AX, and AL are the only registers that data can be moved into or out of, and either a byte-sized immediate value in the instruction or a value in register DX determines which port is the source or destination port of the transfer.

  8. Memory management unit - Wikipedia

    en.wikipedia.org/wiki/Memory_management_unit

    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.
