ARM officially released the Cortex-M55, an AI chip design for IoT devices. It is the first processor core architecture solution based on Arm Helium technology.
The new architecture gives Cortex-M55 the ability to execute SIMD instructions. Digital signal processing capabilities have increased by a factor of five, while machine learning performance has increased by up to 15 times.
In addition, ARM also released a neural processing unit Ethos-U55 , which is designed for low power consumption and needs to be used with Cortex-M series microprocessors. The scale of its processing unit is also scalable, with a minimum of 32 MAC engines and a maximum of 256 MAC engines.
ARM says reducing network links helps privacy protect, and many areas, such as healthcare, process data locally, with little or no need to send results back to a remote server.
Chip products equipped with this design will be available in 2021.
