    <description><![CDATA[<h2 id="pcie">PCIe</h2>
<p>以前有北橋負責讓 CPU -&gt; RAM/GPU，南橋負責到 USB/SATA/PCI/Audio 等，現在南北橋晶片直接融合到 CPU 裡面，並且透過 PCIe 連接，像是：</p>
<ul>
<li>CPU -&gt; GPU</li>
<li>CPU -&gt; SSD</li>
<li>CPU -&gt; 網卡</li>
<li>CPU -&gt; USB Controller</li>
</ul>
<p>以 CPU -&gt; GPU，常常會用 MMIO，MMIO 就是使用 PCIe 實作，並且還會有 DMA。</p>]]></description>
