Hardware, Embedded Systems As expected processor licensor ARM Holdings and Handshake Solutions NV, a Royal Philips Electronics subsidiary, have developed an asynchronous processor based on the ARM9 core. The ARM996HS is thought to be the first commercial clockless processor and is being described as particular suited to use as an automotive microcontroller. Because clockless processors consume zero dynamic power when there is no activity, they can significantly extend battery life compared with clocked equivalents.

I feel a little dubious at this technology. Sure it will save lots of power, but there's never really a time that a CPU is completely idle.

You betcha there is time that a cpu is completely idle. Depending on the use of the system of course, but most cpus in the world spend most of their time doing nothing. They're usually halted, waiting on the next interrupt.
