<h2>Overview</h2>
|
||||
<p>etc-nand is a real-world <a href="https://github.com/ETC-A/etca-spec/">ETC.A</a> CPU built from almost only quad NAND gate ICs (74hc00)</p>
|
||||
<p>It will probably be finished in a few months.</p>

<h3>Estimates</h3>
|
||||
<p>Estimated gate count:</p>
|
||||
<ul>
|
||||
<li>2800 NAND gates</li>
|
||||
<li>320 tristate buffers</li>
|
||||
</ul>
|
||||
<p><br>
|
||||
Estimated component counts:</p>
|
||||
<ul>
|
||||
<li>700x 74hc00 quad NAND gates</li>
|
||||
<li>40x 74HC54 octal tristate buffers</li>
|
||||
<li>a few simple resistors</li>

<h3>Planned Specifications</h3>
|
||||
<p>ETC.A base instruction set + byte operations + S&F + Von Neumann</p>
|
||||
<p>The CPU will communicate with peripherals over a 16 bit data + 15 bit address memory bus</p>
