Operat<strong>in</strong>g State<br />
● If a system supports multiple operat<strong>in</strong>g<br />
po<strong>in</strong>ts, some rules and mechanisms are<br />
required to move the system from one<br />
operat<strong>in</strong>g po<strong>in</strong>t to another.<br />
● Current dynamic control mechanisms may<br />
set operat<strong>in</strong>g po<strong>in</strong>ts <strong>in</strong> response to changes<br />
<strong>in</strong> activity or <strong>in</strong> response to the requests of<br />
key programs.<br />
● low latency of devices, scal<strong>in</strong>g and<br />
un<strong>in</strong>terrupted execution while chang<strong>in</strong>g<br />
states, allows very f<strong>in</strong>e-gra<strong>in</strong> policies. Each<br />
operat<strong>in</strong>g state may be associated with an<br />
operat<strong>in</strong>g po<strong>in</strong>t specific to the requirements<br />
of that state.
