MAX78000 AI microcontroller and Aizip’s Visual Wake Words model bring human-figure detection to IoT image and video at just 0.7 mJ per inference – a 100 times improvement
Maxim Integrated Products, Inc. and Aizip Inc., a company focused on artificial intelligence (AI) for applications in the Internet of Things (IoT), announced that Maxim Integrated’s MAX78000 neural-network microcontroller detects people in an image using Aizip’s Visual Wake Words (VWW) model at just 0.7 millijoules (mJ) of energy per inference. This is 100 times lower than conventional software solutions, and the most economical and efficient IoT person-detection solution available. The low-power network provides longer operation for battery-powered IoT systems that require human-presence detection, including building energy management and smart security cameras.
The MAX78000 low-power, neural-network accelerated microcontroller executes AI inferences at less than 1/100th the energy of conventional software solutions to dramatically improve run-time for battery-powered edge AI applications. The mixed precision VWW network is part of the Aizip Intelligent Vision Deep Neural Network (AIV DNN) series for image and video applications and was developed with Aizip’s proprietary design automation tools to achieve greater than 85 percent human-presence accuracy.

“The MAX78000 architecture, toolchain, and example code and models made it easy to get started and hit our accuracy, latency and power targets on schedule,” said Yuan Lu, Co-Founder and President, Aizip.
“Aizip was quick to exploit our per layer quantization capability to reduce weight storage and achieve a compact, energy-efficient model for human detection. I look forward to working with them on future projects,” said Robert Muchsel, Maxim Integrated Fellow and architect of the MAX78000 microcontroller.
