ARM has announced the Cortex-M0+ CPU, which it is claiming is the world's most energy-efficient processor.

 
The 32-bit processor uses just 9µA/MHz on a low-cost 90nm LP process, a third of the energy used by existing 8-bit or 16-bit processors, while providing a huge boost to performance.
 
The chip is aimed at devices like home appliances, medical monitoring, metering, lighting, and motor control devices, areas that are increasingly becoming known as “the Internet of Things.” All of these can benefit from the low-cost, low-power, and high performance offered by the new Cortex chip.

The CPU also comes with a number of new features, such as a single-cycle IO to speed access to GPIO and peripherals, improved debug and trace capability, and a two-stage pipeline to reduce the number of cycles per instruction and improve Flash accesses, which further reduces power consumption.
 
The Cortex-M0+ employs a model that is particularly suitable for the C programming language and it features binary compatibility with existing Cortex-M0 processors tools and RTOS. It is also compatible with other ARM software for Cortex processors.
 
Freescale and NXP Semiconductor have already agreed to licence the Cortex-M0+ processor, and considering the fact that 50 companies licensed the previous Cortex-M0 processor, we can likely expect to see many other firms show their support.
