STM32N6 vs STM32MP257 - Which one have the best AI?

[DMårt]

I have seen a lot of videos on YouTube where STM32N6 demonstrates incredible AI features such as multiple pose estimation, multiple object detection and multiple object classification at the same time.

But I haven't seen anything similar for STM32MP257. So my question is: If I want to start with AI on embedded systems, which one of them two should I use?

Well, N6 is built with AI in mind and has dedicated resources for that !

@mbarg.1 

Can you elaborate that?

From STM web site STM32N6 series - STMicroelectronics :

The STM32N6 is the first STM32 MCU to embed the ST Neural-ART accelerator™, an in-house developed neural processing unit (NPU) engineered for power-efficient edge AI applications. Clocked at 1 GHz and providing up to 600 GOPS, it enables real-time neural network inference for computer vision and audio applications.

A dedicated computer vision pipeline with a MIPI CSI-2 interface and image signal processing (ISP) ensures compatibility with a wide range of cameras. The STM32N6 also features an H264 hardware encoder and the NeoChrom™ Accelerator for graphics, making it suitable for feature-rich products.

It offers 4.2 Mbytes of contiguous embedded RAM, ideal for neural networks or graphics applications, complemented by high-speed external memory interfaces (hexa-SPI, OCTOSPI, FMC).

Can anyone from ST show me some demonstrations for the STM32MP257 when AI is used?
