ARM director of marketing Jeff Chu unveiled the new Cortex-M chip designs at Computex in Taipei on Monday, where he said the processor manufacturer was looking to almost double battery life, for IoT devices.
The restructured Cortex-M also boasts support for a new Bluetooth 4.2 radio called Cordio, and has a new memory subsystem that will enable faster exchange of data between components. Additionally, a wide range of sensors can be applied to the chips.
ARM showed chips based on the new design at a news conference at Computex. A developer board with the Cordio-based Bluetooth chip was able to measure ambient temperature and transmit the readings to a smartphone.
The company intends to add more wireless connectivity options to its IoT chip designs too, Patel said. It hopes to add support for the 802.15.4 standard, which is the basis for Zigbee, a low-power wireless data transfer protocol that competes with Bluetooth.
With the redesign, ARM is also trying to speed up the development of chips for IoT devices, which could number more than 50 billion by 2020, said Dipesh Patel, executive vice president of technical operations at ARM.
ARM designed the new development platform to work with its mbed OS for the Internet of Things. A wine rack on display at the news conference used the Raspberry Pi and mbed OS to check the inventory and temperature of a wine rack, with the information transmitted to apps on mobile devices via the Amazon cloud service.
