Deep Learning Inference Engine “SoftNeuro®” Is Compatible with the AI Accelerator of Renesas’ “R-Car” SoC: Realize Rapid Implementation and High-Speed Computing


Tokyo, Japan – December 10th, 2021– Morpho, Inc. (hereinafter, “Morpho”), a global leader in image processing solutions and imaging AI solutions, announced today that “SoftNeuro®”, one of the world’s fastest deep learning inference engines, is now compatible with CNN-IP, the AI accelerator engine on the R-Car SoC for automotive from Renesas.


R-Car’s “CNN-IP” is an AI accelerator capable of high-speed processing that can meet these demands. On the other hand, “CNN-IP” requires a dedicated development environment to convert any AI learning model based on TensorFlow or ONNX into a format for “CNN-IP,” which requires a certain amount of man-hours to implement.


“SoftNeuro”, which is compatible with CNN-IP, optimizes AI learning models to an appropriate format for a dedicated development environment, and thus can execute high-speed operations immediately. As a result, the implementation period can be reduced to as little as one day.

The demo content of Renesas Automotive Days, a global online event hosted by Renesas and held from October to December this year, is posted on the following website.
