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.
Each sprite is either 8×8 or 16×16 pixels and can be scaled 2× to 16×16 or 32×32. 16 KB of RAM is provided for the Video Display Processor. VDP RAM is the largest block of writeable memory in the unexpanded TI-99/4A architecture, and is used for storing disk I/O buffers and TI BASIC user programs.
The single fixed-screen mode used in first-generation (128k and 512k) Apple Mac computers, launched in 1984, with a monochrome 9" CRT integrated into the body of the computer. Used to display one of the first mass-market full-time GUIs, and one of the earliest non-interlaced default displays with more than 256 lines of vertical resolution.
Despite improving product quality and the Honeywell repair partnership, the company could not improve the computer's poor reputation. [16] Problems included: The Adam generates a surge of electromagnetic energy on startup, which can erase the contents of any removable media left in or near the drive. [2]
Example video in 16K (16000 × 9000 pixels) A VR video in 16K (16000 × 8000 pixels) 16K resolution is a display resolution with approximately 16,000 pixels horizontally. The most commonly discussed 16K resolution is 15360 × 8640, which doubles the pixel count of 8K UHD in each dimension, for a total of four times as many pixels. [1]
The controller can then continue to use the DRAM port for drawing objects on the display. Meanwhile, the controller feeds a clock called the shift clock (SCLK) to the VRAM's video port. Each SCLK pulse causes the VRAM to deliver the next data [computing] in strict address order, from the shift register to the video port. For simplicity, the ...
The original IBM CGA graphics card was built around the Motorola 6845 display controller, [2] came with 16 kilobytes of video memory built in, and featured several graphics and text modes. The highest display resolution of any mode was 640 × 200, and the highest color depth supported was 4-bit (16 colors).
The GPU having access to a large L2 or L3 cache allows it to more quickly access necessary data compared to accessing VRAM or system RAM. The Infinity Cache is made up of two sets of 64 MB cache that can run on its own clock rate independent from the GPU cores.
