  2. Shared graphics memory - Wikipedia

    en.wikipedia.org/wiki/Shared_graphics_memory

    Graphics display was facilitated by the use of an expansion card with its own memory plugged into an ISA slot. The first IBM PC to use the SMA was the IBM PCjr, released in 1984. Video memory was shared with the first 128 KiB of RAM. The exact size of the video memory could be reconfigured by software to meet the needs of the current program.

  3. Windows Display Driver Model - Wikipedia

    en.wikipedia.org/wiki/Windows_Display_Driver_Model

    Shared graphics power components, allowing non-graphics drivers to participate in the power management of a graphics device. Shared texture improvements , increasing the types of textures that can be shared across processes and Direct3D devices, adding support to monochrome with minimal memory copying.

  4. Graphics address remapping table - Wikipedia

    en.wikipedia.org/wiki/Graphics_address_remapping...

    The graphics address remapping table (GART), [1] also known as the graphics aperture remapping table, [2] or graphics translation table (GTT), [3] is an I/O memory management unit (IOMMU) used by Accelerated Graphics Port (AGP) and PCI Express (PCIe) graphics cards. The GART allows the graphics card direct memory access (DMA) to the host system ...

  5. Video random-access memory - Wikipedia

    en.wikipedia.org/wiki/Video_random-access_memory

    GDDR5X SDRAM on an NVIDIA GeForce GTX 1080 Ti graphics card. Video random-access memory (VRAM) is dedicated computer memory used to store the pixels and other graphics data as a framebuffer to be rendered on a computer monitor. [1] It often uses a different technology than other computer memory, in order to be read quickly for display on a screen.

  6. Desktop Window Manager - Wikipedia

    en.wikipedia.org/wiki/Desktop_Window_Manager

    DWM works in different ways depending on the operating system (Windows 7 or Windows Vista) and on the version of the graphics drivers it uses (WDDM 1.0 or 1.1). Under Windows 7 and with WDDM 1.1 drivers, DWM only writes the program's buffer to the video RAM, even if it is a graphics device interface (GDI) program.

  7. Shared memory - Wikipedia

    en.wikipedia.org/wiki/Shared_memory

    HSA defines a special case of memory sharing, where the MMU of the CPU and the IOMMU of the GPU have an identical pageable virtual address space.. In computer hardware, shared memory refers to a (typically large) block of random access memory (RAM) that can be accessed by several different central processing units (CPUs) in a multiprocessor computer system.

  8. Video BIOS - Wikipedia

    en.wikipedia.org/wiki/Video_BIOS

    Generic components of a graphics card. Note that the VGABIOS is a separate chip located on the graphics card, and not part of the GPU. Practically all processing units require basic initialization, not just GPUs. Video BIOS is the BIOS of a graphics card in a (usually IBM PC-derived) computer. It initializes the graphics card at

  9. User-Mode Driver Framework - Wikipedia

    en.wikipedia.org/wiki/User-Mode_Driver_Framework

    Badly written device drivers can cause severe damage to a system (e.g., BSoD or data corruption) since all standard drivers have high privileges when accessing the kernel directly. The User-Mode Driver Framework insulates the kernel from the problems of direct driver access, instead providing a new class of driver with a dedicated application ...
