Famous Graphics Chips: EGA to VGA - IEEE Computer Society
2018年11月15日 · VGA IBM’s video graphics array was the most significant graphics chip to ever be produced in terms of volume and longevity. The VGA was introduced with the IBM PS/2 line of computers in 1987, along with the 8514. The two AIBs shared an output connector which became the industry standard for decades, the VGA connector.

2025年1月10日 · Historically, the predecessor of the VGA - the EGA - had several chips to perform each part in the system. These chips could be configured to your liking using the I/O Bus. On the VGA, these have been merged into one chip (with the exception of the DAC). The following diagram shows which units are responsible for which parts:
The LCD driver on this board (the chip that takes in video signals and translates them into what the LCD needs) accepts standard VGA signals (the same signals that would be used to drive a monitor) for sending pixel data as well as an extra signal for enabling and disabling the backlight (MTL2_BL_ON_n).
从零开始设计并实现VGA显卡 - 知乎
要设计 VGA显卡,我们首先要了解 VGA接口,它长这样: VGA接口一共有15针,排列为3行: 其中,引脚1~3是RGB模拟信号,不同的电压表示不同的RGB分量。 引脚13和引脚14是行场同步信号,剩下的大都是接地信号。 VGA显示的原理就是逐行扫描,在两个行同步信号之间,要完成一行像素点数据的扫描: 场同步则是指在两个场同步信号之间,要完成一整屏的数据扫描,对于640x480分辨率来说,在两个场同步信号之间,要完成480个行同步信号: 根据VGA规 …

What is VGA? - How-To Geek
2022年8月19日 · VGA (short for Video Graphics Array) is an analog video standard created by IBM in 1987 for the IBM PS/2 series of computers. Since then, the computer industry has extended the standard and included it in millions of products. VGA uses a high-density 15-pin D-sub connector (called DE-15), often with two thumb screws to secure the connector in ...
VGA/SVGA Video Programming--Standard VGA Chipset Reference
The VGA hardware is complex and can be confusing to program. Rather than attempt to document the VGA better than existing references by using more words to describe the registers, this section breaks down the functionality of the VGA into specific categories of similar functions or by detailing procedures for performing certain operations.
