In computing, a screen buffer is a part of computer memory used by a computer application for the representation of the content to be shown on the computer display. [3] The screen buffer may also be called the video buffer, the regeneration buffer, or regen buffer for short. [4] Screen buffers should be distinguished from video memory. To this ...
Uniform memory access (UMA) is a shared memory architecture used in parallel computers.All the processors in the UMA model share the physical memory uniformly. In an UMA architecture, access time to a memory location is independent of which processor makes the request or which memory chip contains the transferred data.
In DOS memory management, the upper memory area (UMA) is the memory between the addresses of 640 KB and 1024 KB (0xA0000–0xFFFFF) in an IBM PC or compatible. IBM reserved the uppermost 384 KB of the 8088 CPU 's 1024 KB address space for BIOS ROM , Video BIOS , Option ROMs , video RAM, RAM on peripherals, memory-mapped I/O , and obsoleted ROM ...
In computing, hardware overlay, a type of video overlay, provides a method of rendering an image to a display screen with a dedicated memory buffer inside computer video hardware. The technique aims to improve the display of a fast-moving video image — such as a computer game, a DVD, or the signal from a TV card.
The remaining 384 KB beyond the conventional memory area, called the upper memory area (UMA), was reserved for system use and optional devices. UMA was used for the ROM BIOS , additional read-only memory , BIOS extensions for fixed disk drives and video adapters, video adapter memory, and other memory-mapped input and output devices .
DirectFB (Direct Frame Buffer), now continued as DirectFB2, is a software library with a small memory footprint that provides graphics acceleration, input device handling and abstraction layer, and integrated windowing system with support for translucent windows and multiple display layers on top of the Linux framebuffer without requiring any kernel modifications.

Shadow buffer A synonym for shadow map. Shadow map A texture buffer holding depth values rendered in a separate render pass from the perspective of a lightsource, used in Shadow mapping; it is typically rendered onto other geometry in the main rendering pass. [29] Shadow volume One of the techniques of adding shadows to 3D scenes. Signed ...
