Renesas expands its AI-capable RZ/V Series of microprocessors

By Michelle Froese September 29, 2022

Renesas Electronics Corporation, a supplier of advanced semiconductor solutions, has expanded its AI-capable RZ/V Series of microprocessors (MPUs), with a new device that enables AI processing of image data from multiple cameras — offering a new level of highly accurate image recognition for vision AI applications.

Equipped with two 64-bit Arm Cortex-A53 cores, the new device is capable of delivering high computing performance with a maximum operating frequency of 1GHz. The RZ/V2MA features a proprietary low-power dynamically reconfigurable processor (DRP-AI) accelerator, which can process vision AI at 1 TOPS/W (tera operations per second, per watt) class performance.

The RZ/V2MA device offers high-speed interfaces such as Ethernet, USB, and PCI Express, allowing image input from multiple external cameras. In addition to the DRP-AI accelerator, the RZ/V2MA includes an OpenCV accelerator that allows rule-based image processing simultaneously.

These features bring highly accurate image recognition capabilities for machine vision products such as AI-equipped gateways, video servers, security gates, POS terminals, and robotic arms.

“One of the challenges for embedded systems developers who want to implement machine learning is to keep up with the latest AI models that are constantly evolving,” said Shigeki Kato, VP of Renesas’ Enterprise Infrastructure Business Division. “With the new DRP-AI TVM tool, we are offering designers the option to expand AI frameworks and AI models that can be converted to executable formats, allowing them to bring the latest image recognition capabilities to embedded devices using new AI models.”

The new RZ/V2MA offers a full suite of development tools to aid vision AI system design. In addition to the existing DRP-AI Translator, the new device adds DRP-AI TVM (Note 1), which is based on the open-source deep learning compiler Apache TVM technology (Note 2).

While DRP AI Translator is designed to convert AI models into DRP-AI executables, the DRP-AI TVM compiler lets the DRP-AI accelerator work together with the CPU, allowing DRP-AI to convert and generate more AI models than ever before. As a first phase, Renesas supports ONNX and PyTorch AI models and plans to support Tensorflow in the future.

“Renesas’ RZ/V series is ideal for embedded devices since it does not need fans or heat sinks, due to its extremely low power consumption and low heat capability when running AI,” said Chiharu Nakabayashi, president of amnimo Inc., a provider of IoT and AI-based services and a wholly owned subsidiary of Yokogawa Electric Corporation. “With these devices, we are confident that we can develop powerful image AI gateways that can be installed anywhere.”
