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.
Dual-ported video RAM (VRAM) is a dual-ported RAM variant of dynamic RAM (DRAM), which was once commonly used to store the Framebuffer in Graphics card, . Dual-ported RAM allows the CPU to read and write data to memory as if it were a conventional DRAM chip, while adding a second port that reads out data.
Freeswitch, an open-source telephony platform, can make use of Lua as a scripting language for call control and call flow among other things. Garry's Mod, a sandbox video game, uses Lua for mods, called addons, published on the Steam Workshop. Geany, a code editor, has a Lua plugin, GeanyLua.
The GPU uses those instructions to compute the rasterized results and the results are bit blitted to the framebuffer. The framebuffer's signal is then produced in combination with built-in video overlay devices (usually used to produce the mouse cursor without modifying the framebuffer's data) and any final special effects that are produced by ...
Various methods to achieve video overlay are in use: A video overlay device can be connected between the graphics card analog VGA output and the monitor's input, forming a "VGA passthrough". The device modifies the VGA signal and inserts the analog video signal overlay into the picture; the rest of the screen is filled by the signal coming from ...
FMOD Studio low-level API - A programmer API that stands alone, with a simple interface for playing sound files, adding special effects and performing 3D sound. Legacy products include: FMOD Ex - The sound playback and mixing engine.
WDDM drivers allow video memory to be virtualized, [6] and video data to be paged out of video memory into system RAM. In case the video memory available turns out to be insufficient to store all the video data and textures, currently unused data is moved out to system RAM or to the disk. When the swapped out data is needed, it is fetched back.
An overlay manager, either part of the operating system or part of the overlay program, loads the required overlay from external memory into its destination region when it is needed; this may be automatic or via explicit code.
