ARM Offers First Clockless Processor Core 351

Sam Haine '95 writes "EETimes is reporting that ARM Holdings have developed an asynchronous processor based on the ARM9 core. The ARM996HS is thought to be the world's first commercial clockless processor. ARM announced they were developing the processor back in October 2004, along with an unnamed lead customer, which it appears could be Philips. The processor is especially suitable for automotive, medical and deeply embedded control applications. Although reduced power consumption, due to the lack of clock circuitry, is one benefit the clockless design also produces a low electromagnetic signature because of the diffuse nature of digital transitions within the chip. Because clockless processors consume zero dynamic power when there is no activity, they can significantly extend battery life compared with clocked equivalents."
