<h1>Microcode compilation </h1> </div>
</div>
<div class="contents">
<p>The <a class="el" href="classao68000.html" title="ao68000 top level module.">ao68000</a> microcode is represented as an Java program. Execution of this program results in generating the binary microcode.</p>
<h3>Microcode operations</h3>
<p>All possible microcode operations are described at the beginning of <code>./rtl/ao68000.v</code>. The locations of:</p>
<ul>
<li>each operation in the microcode word,</li>
<li>every procedure in the microcode</li>
</ul>
<p>are auto-generated and inserted to the same file. All the available operation are also represented as Java functions and saved in an auto-generated file, located at <code>./sw/ao68000_tool/Parser.java</code> (<a class="el" href="page_microcode_operations.html">Microcode operations</a>). This auto-generated data is generated by the tool <code>./sw/ao68000_tool/</code> (<a class="el" href="page_tool.html">ao68000_tool documentation</a>).</p>
<h3>Microcode compilation</h3>
<p>The source for the microcode is located at <code>./sw/ao68000_tool/Microcode.java</code> (<a class="el" href="page_microcode.html">Microcode</a>).</p>
<p>The compiled microcode, in Altera MIF format, is located at <code>./rtl/ao68000_microcode.mif</code>.</p>
<p>The tool <code>./sw/ao68000_tool/</code> (<a class="el" href="page_tool.html">ao68000_tool documentation</a>) is used to compile the microcode source and transform it into a MIF file. The makefile containing instructions for performing the compilation is located at <code>./Makefile</code>. </p>
