<title>Performance</title>
<para>
<emphasis>vport</emphasis> is similar to <link linkend="port"><citetitle>port</citetitle></link>, but operates with vectorial signals, instead of with scalar signals. Each vector element is treated as an independent control signal. Input and output vectors are placed in the same table and output vector overrides input vector. If you want to keep input vector, use <link linkend="vcopy"><citetitle>vcopy</citetitle></link> opcode to copy it in another table.
