UK based chip designer ARM has unveiled its smallest, lowest power 32-bit core designed for the Internet of Things, wearables and embedded systems. According to the company, the Cortex-A32 is ARM's smallest and most power-efficient core yet.

ARM is also partnering with Hewlett-Packard Enterprise (HPE) to enable greater device interoperability in industrial IoT systems and applications designed for industrial automation, smart cities, environmental monitoring and smart lighting.

The Cortex-A32, a 32-bit processor built on the ARMv8-A architecture, is 25 percent more efficient than the current leading ARM embedded 32-bit core, the Cortex-A7, and delivers higher performance while using less power. In its smallest configuration, the Cortex-A32 occupies less than 0.25 mm2 of silicon area while consuming less than 4mW of total power at 100 MHz in a 28nm process node.
The Cortex-A32 can be configured in multiple ways from single- to quad-core. This makes it scalable enough to serve the smallest and most efficient compute devices through to Internet of Things (IoT) gateways and industrial compute applications.

Cortex-A class processors are found in applications from automotive infotainment and industrial controllers to robots and wearable devices.

"ARM offers an unrivalled portfolio of processors that power billions of extremely efficient embedded devices," said James McNiven, general manager, CPU group. "The Cortex-A32 processor, enabled with secure ARM TrustZone® technology, builds on the trail blazed by the Cortex-A5 and Cortex-A7 processors in embedded applications such as single-board computing, IoT edge nodes and wearables. It brings greater performance, efficiency and other benefits of the ARMv8-A architecture for ARM's silicon partners to innovate on for richer, more secure embedded systems."

The collaboration with between ARM and HPE is aimed at accelerating industrial IoT by enabling greater device interoperability.

The partnership aims to tackle the current difficulty of building network systems of connected IoT devices due to the prevalence of proprietary standards or non-interoperable industry standards. According to ARM, this can make it impossible for devices to share information and it limits the capability of an IoT network.

The collaboration addresses this issue by enabling devices to be centrally identifiable, accessible and manageable. This will be achieved by HPE using ARM® mbed™ IoT Device Platform connectivity solutions that integrate all device hardware and software, manage operational deployment and facilitate analysis of device intelligence. The highly scalable solution is built on open standards and utilizes chip-to-cloud device security offered by mbed technology. It will allow enterprises to benefit from accelerated time to market and lower cost of ownership.

"Our IoT technology partnership with ARM can revolutionize connectivity moving forward," said Dave Sliter, vice president and general manager, Communications & Media Solutions, HPE. "The collaboration has the potential to bring new IoT solutions to market quickly and accelerate adoption in the enterprise of smart connected technologies."

The solution can be adjusted based on individual device to service needs. Built on open-standards and supported through open source software, the platform provides a future proof solution that will allow enterprise developers to focus on their core expertise (device or application development) rather than platform enablement and integration.

"The ARM and Hewlett Packard Enterprise solution will simplify the deployment of industrial IoT networks," said Dipesh Patel, executive vice president, Incubation Businesses, ARM. "It will provide a secure standard-based way of networking any number of connected devices. This offers the kind of scalable deployments companies need to deal efficiently with future growth."
