The Dynamic–Static Interface<br />
In order to underst<strong>and</strong> the DSI, we must place it within the context of a <strong>com</strong>piler for a<br />
higher–level language. Although most <strong>com</strong>pilers do not emit assembly language, we<br />
shall find it easier to under the DSI if we pretend that they do.<br />
What does the <strong>com</strong>piler output? There are two options:<br />
1. A very simple assembly language. This requires a sophisticated <strong>com</strong>piler.<br />
2. A more <strong>com</strong>plex assembly language. This may allow a simpler <strong>com</strong>piler,<br />
but it requires a more <strong>com</strong>plex control unit. If <strong>com</strong>plex enough, parts of the<br />
control unit are probably microprogrammed.
