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.
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 ...
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.
An extension to VGA defined by VESA for IBM PC-compatible computers in 1989 meant to take advantage of video cards that exceeded the minimum 256 kB defined in the VGA standard. For instance, one of the early supported modes was 800×600 in 16 colours at a slightly lower 56 Hz refresh rate, leading to 800×600 sometimes being referred to as ...
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]
These colors can be chosen independently, for each character on the screen, from the full 16-color CGA palette. The character set is defined by hardware code page 437 . The font bitmap data is only available to the card itself, it cannot be read by the CPU.
BG tiles on screen: 512 (16×16 tiles in 256×256 layers) to 4096 (8×8 tiles in 512×512 layer) Sprite plane [5] [9] [10] Sprite count: 128 sprites on screen, 32 sprites per scanline, 256 sprite patterns in VRAM (can be multiplied up to 512 sprites on screen with scanline raster interrupt method [11]) Sprite size: 16×16
The Compaq Contura Aero 4/25 and 4/33c were among the earliest subnotebook computers that acted as a precursor to netbooks. They were released in 1994 and originally ran MS-DOS and Windows 3.1. They were also able to run Windows 95 after its release in 1995. They were similar to the Armada line of laptop computers, but smaller. Although the 4/ ...
