	<h1 class="post-title">收集了一些前期的图像视频芯片的信息</h1>
	<span class="post-date">周一 16 一月 2023</span>
	<p>现代的计算机系统，无论是台式电脑、笔记本、手机、游戏机，基本上都有专门的图形芯片，用于图像的输出。今天，我们一般将这种图形芯片，称为GPU（Graphic Processing Unit），即图形处理单元。</p>
<p>除了一些作为控制器使用MCU系统，一般的通用型计算机系统，都包括了CPU。在PC上，GPU在显卡上存在。而手机等系统，GPU则作为SoC（System on a Chip）的一部分，在主芯片上存在。</p>
<p>在计算机的发展早期，是没有专门的芯片用于图像输出的，早期的计算机系统甚至没有图像输出。后来计算机越来越为个人所使用，图像输出变得重要起来。于是就有了专门的芯片。</p>
<p>本篇记录和罗列一些我收集到的前期图像视频芯片的信息，后面会做陆续更新。</p>
<p>早期图像视频芯片是没有统一的名称的，所以需要罗列一下：</p>
