<p>I guess I haven&#39;t been paying enough attention, but Intel&#39;s APX is a really big update to their ISA:<br />- 32 GP registers<br />- setting flags is optional in many cases<br />- instructions take 3 operands instead of 2</p><p><a href="https://www.intel.com/content/www/us/en/developer/articles/technical/advanced-performance-extensions-apx.html" target="_blank" rel="nofollow noopener" translate="no"><span class="invisible">https://www.</span><span class="ellipsis">intel.com/content/www/us/en/de</span><span class="invisible">veloper/articles/technical/advanced-performance-extensions-apx.html</span></a></p>

<p>this also means that if you want to make an applet that is &quot;just&quot; some existing applet plus some GPIO straps, this can be done with just 2 lines of code:</p><p>self.gpio_iface = GPIOInterface(self.logger, self.assembly, pins=(args.reset,))<br />await self.gpio_iface.output(0, 1)</p>

<p>it is now possible to set arbitrary strap pins with <a href="https://mastodon.social/tags/GlasgowInterfaceExplorer" class="mention hashtag" rel="tag">#<span>GlasgowInterfaceExplorer</span></a>! use `glasgow multi &lt;...&gt; ++ gpio --pins B0:3 B0=0 B1=H B2=L B3=1` to strap B0 strong low, B1 weak high, B2 weak low, B3 strong high</p><p>the GPIO applet doesn&#39;t take up USB endpoint resources, so this is &quot;free&quot;: you can append `++ gpio` to any applet command line you&#39;d like</p>

<p>I decided to also end with a completely gratuitous, and frankly, uncalled for macro example. This really amped up the level of crazy more than it already was.</p>
