ARM released the ultra-small core Cortex-A32, focusing on ultra-low power consumption

Recently, semiconductor IP supplier ARM launched ARM Cortex-A32 for the next generation of embedded products, the new member uses the ARMv8-A architecture, which is a 32-bit embedded application processor core, compared to other similar productsprocessorThe Cortex-A32 has the smallest footprint and the best energy efficiency.

According to James McNiven, general manager of ARM's processor division, the Cortex-A32 processor uses ARM TrustZone security technology and inherits the foundation laid by the Cortex-A5 and Cortex-A7 processors in embedded applications, such as single-board computing, IoT edge nodes and wearable devices. With the advantages of ARMv8-A architecture in performance and power consumption, it helps partners quickly develop diversified embedded systems.

At present, the Cortex-A5 and Cortex-A7 processors of the ARMv7-A architecture are two widely adopted application processors in the industry and have become the core of many embedded applications. The 32-bit processor Cortex-A32 on the ARMv8-A architecture delivers up to 25% less energy efficiency than the 32-bit embedded core Cortex-A7. In the smallest configuration, the Cortex-A32 occupies less than 0.25 millimeters of chip size, while the total power consumption of the 100MHz 28nm process node is less than 4 milliwatts.

The Cortex-A32 supports a variety of configuration modes, from single-core to quad-core. As a result, the Cortex-A32 is highly scalable to support not only the smallest and most energy-efficient computing devices, but also IoT gateways and industrial computing applications.

Maarten Ectors, vice president of Canonical's IoT division, said: "IoT nodes are becoming more diverse, and the more complex nodes are, the more complex the operating systems are usually required. Combining the Snappy Ubuntu core with the ultra-energy-efficient processing power and scalability of the Cortex-A32 will help developers further expand the scope of IoT devices.
