The first commercial use of VRAM was in a high-resolution graphics adapter introduced in 1986 by IBM for its IBM RT PC system, which set a new standard for graphics displays. Prior to the development of VRAM, dual-ported memory was quite expensive, limiting higher resolution bitmapped graphics to high-end workstations.
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.
Sun TGX Framebuffer. A framebuffer (frame buffer, or sometimes framestore) is a portion of random-access memory (RAM) [1] containing a bitmap that drives a video display. It is a memory buffer containing data representing all the pixels in a complete video frame. [2]
In computer architecture, shared graphics memory [1] refers to a design where the graphics chip does not have its own dedicated memory, and instead shares the main system RAM with the CPU and other components.
Random-Access Neural Compression of Material Textures (Neural Texture Compression) is a Nvidia's technology which enables two additional levels of detail (16x more texels, so four times higher resolution) while maintaining similar storage requirements as traditional texture compression methods.
SGRAM is single-ported. However, it can open two memory pages at once, which simulates the dual-port nature of other VRAM technologies. It uses an 8N-prefetch architecture and DDR interface to achieve high performance operation and can be configured to operate in ×32 mode or ×16 (clamshell) mode which is detected during device initialization.
In computer graphics, planar is the method of arranging pixel data into several bitplanes of RAM.Each bit in a bitplane is related to one pixel on the screen. Unlike packed, high color, or true color graphics, the whole dataset for an individual pixel is not in one specific location in RAM, but spread across the bitplanes that make up the display.
An enlargement of a small section of a 1024x768 (VESA XGA) resolution image; the individual pixels are more visible in its scaled form than its normal resolution.A video scaler is a system that converts video signals from one display resolution to another; typically, scalers are used to convert a signal from a lower resolution (such as 480p standard definition) to a higher resolution (such as ...
