Vision AI MPUs for real-time human, object recognition
Renesas Electronics Corporation has introduced a series of microprocessors (MPUs) featuring the company's vision-optimized artificial intelligence (AI) accelerator targeted at cameras used in industrial, infrastructure, and retail applications.

Featuring the company's DRP-AI (Dynamically Reconfigurable Processor), the RZ/V MPUs are designed to meet the demand for real-time, AI-based person and object recognition functionality in applications such as surveillance cameras for industrial and infrastructure as well as product scanners and POS terminal cameras. The first product in the series, the RZ/V2M, is designed to deliver a combination of real-time AI inference and "industry-leading" power efficiency in embedded devices.

"The new RZ/V Series delivers both high performance and low power consumption, the two key issues that are keeping Vision AI processing from achieving a higher level of real-time performance," says Hiroto Nitta, Senior Vice President, Head of SoC Business, IoT and Infrastructure Business Unit at Renesas. "The RZ/V Series will dramatically expand the range of AI applications in embedded devices through object recognition, for example cameras in smart shopping cart systems that automatically calculate totals based on the cart items, robots in factories that can safely work together with humans, and medical cameras that assist doctors in making diagnoses."

The RZ/V2M offers a power consumption as low as 4W (typ.), eliminating the need for heat sinks and cooling fans, greatly simplifying heat dissipation measures. This enables RZ/V2M to be used in compact devices and helps to minimize equipment sizes, says the company, expanding the opportunities to incorporate AI in embedded devices. It also helps to reduce bill-of-materials (BOM) costs.

In addition to the DRP-AI, the RZ/V2M features an imaging signal processor (ISP) capable of processing high-resolution 4K pixels at 30 frames per second. The ISP employs high dynamic range (HDR) functionality capable of handling images with large differences between brightness and darkness, noise reduction functionality, and distortion correction functionality to substantially boost precision in AI recognition, says the company, ensuring the ability to produce clear images regardless of factors such as the weather, the time of day, and the installation location.
