<p>以下演示了 CherryUSB 在不同应用中的性能表现。主要演示高速模式，全速看不出什么性能差异。</p>
<section id="cdc-acm">
<h2>CDC ACM 通信<a class="headerlink" href="#cdc-acm" title="Link to this heading"></a></h2>
<p>可以达到硬件极限性能，当然需要硬件理论支持到这速度，CherryUSB 就支持到这速度,举例如下：</p>
<ul class="simple">
<li><p>HPM 系列(从机可以到 42MB/S, 主机 44MB/S, 已经达到硬件极限)</p></li>
<li><p>BL 系列（从机 32MB/S, 主机 25MB/S, 已经达到硬件极限）</p></li>
<li><p>STM32F4 全速（从机 900KB/S, 主机 1.12MB/S, 已经达到硬件极限）</p></li>
</ul>
<p>从机测速demo: cdc_acm_template.c 并且关闭 log，脚本使用 <cite>tools/test_srcipts/test_cdc_speed.py</cite>
主机测速demo: usb_host.c 中 TEST_USBH_CDC_SPEED=1</p>
