ARM Cortex-A32 emerges as a 32-bit solution for wearables and IoT devices

ARM Holdings has joined the ongoing Mobile World Congress (MWC) to announce the Cortex-A32 as its first application processor for wearables and IoT devices. The new 32-bit processor is designed to bring the benefits of the ARMv8-A architecture to the world of connected devices.

The ARM Cortex-A32 is claimed to be 25 percent more energy efficient than the currently available Cortex-A7. It comes in a small configuration to occupy less than 0.25mm2 of silicon area in a device with the power consumption of 4mW at 100MHz in a 28nm process node.

ARM last year brought Cortex-A35 for affordable smartphones that set the ground for the new Cortex-A32. The new processor IP is capable of handle processing through the latest software, mainly Linux-based Android operating system. Moreover, it can be configured with multiple cores.

The Cortex-A32 comes equipped with ARM TrustZone technology that deploys security through cryptographic hardware acceleration and an advanced root of trust. Further, vendors can configure cache sizes to customise the performance of the processor from 8KB to 32GB in L1 and up to 1MB in L2.

ARM hasn’t specified any of the devices for which the Cortex-A32 will be available. However, it is designed for wearables like smartwatches and smart wristbands as well as IoT devices and embedded systems and mini PCs including the Raspberry Pi.

The ARM Cortex-A32 will be available to hardware vendors by the end of 2017.
