Renesas Electronics expanded this week its range of embedded artificial intelligence (e-AI) solutions for incorporating AI into embedded systems by bringing intelligence to endpoints. Approximately 150 companies in more than 10 countries worldwide are already conducting trials based on this technology, and there are more than 30 actual e-AI use cases underway.
Renesas RZ/A2M is suitable for applications using HMI (Human Machine Interface), among others, cameras. It corresponds to the MIPI camera interface which is used in mobile devices and incorporates DRP (Dynamically Reconfigurable Processor), which processes the input image at high speed.
In addition to installing two Ethernet channels, security is enhanced by a cryptographic hardware accelerator. The network connection becomes safe and secure, and it can be applied to image recognition application of a wide range of systems from home electronics to industrial equipment.
Renesas developed the RZ/A2M microprocessor (MPU) to expand the use of e-AI solutions to high-end applications. The new MPU delivers ten times image processing performance of its predecessor, the RZ/A1, and incorporates Renesas’ Dynamically Reconfigurable Processor, which achieves real-time image processing at low power consumption.
This allows applications incorporating embedded devices – such as smart appliances, service robots, and compact industrial machinery – to carry out image recognition employing cameras and other AI functions, while maintaining low power consumption, and accelerating the realization of intelligent endpoints.
The RZ/A2M with DRP is a new addition to the RZ/A Series lineup of MPUs equipped with large capacity on-chip RAM, which eliminates the need for external DRAM. The RZ/A Series MPUs address applications employing human-machine interface (HMI) functionality, and the RZ/A2M adds to this capability with features ideal for applications using cameras. It supports the MIPI camera interface, used in mobile devices, and comes equipped with a DRP for high-speed image processing.
Renesas has also boosted network functionality with the addition of two-channel Ethernet support, and enhanced secure functionality with an on-chip hardware encryption accelerator. These features enable safe and secure network connectivity, making the new RZ/A2M best suited for a wide range of systems employing image recognition, from home appliances to industrial machinery.
Currently, there are several challenges to using AI in the operational technology (OT) field, such as difficulty transferring large amounts of sensor data to the cloud for processing, and delays waiting for AI judgments to be transferred back from the cloud. Renesas already offers AI unit solutions that can detect previously invisible faults in real time by minutely analyzing oscillation waveforms from motors or machines.
To accelerate the adoption of AI in the OT field, Renesas has developed the RZ/A2M with DRP, which makes possible image-based AI functionality requiring larger volumes of data and more powerful processing performance than achievable with waveform measurement and analysis. Since real-time image processing can be accomplished while consuming very little power, battery-powered devices can perform tasks such as real-time image recognition based on camera input, biometric authentication using fingerprints or iris scans, and high-speed scanning by handheld scanners. This solves several issues associated with cloud-based approaches, such as the difficulty of achieving real-time performance, assuring privacy, and maintaining security.
“The adoption of e-AI will bring incalculable advances in convenience, safety, and production efficiency,” said Yoshikazu Yokota, executive vice president and general manager for the industrial solution business unit at Renesas. “We have successfully improved production yields at our own factories through the use of e-AI, proving the usefulness of AI for endpoints. We will continue expanding the scope of e-AI applications from simple attributes such as colors, shapes, and waveforms to complex image processing in real time. Renesas will also offer e-AI solutions that anyone can use, and lead the way in bringing intelligence to endpoints.”
Samples of the RZ/A2M with DRP are available now. The RZ/A2M MPUs are offered with a development board, reference software, and DRP image-processing library, allowing customers to begin evaluating HMI function and image processing performance. Mass production is scheduled to start in the first quarter of next year, and monthly production volume for all RZ/A2M versions is anticipated to reach a combined 400,000 units by 2021.
