Looking For a Graphic Co-Processor for My Boards

03/19/2017 4:06 PM

Good morning,

I am looking for a graphic co-processor chip or PCB to add to my embedded processor boards used with industrial equipment.

My boards presently use the STM32F4xx micro-controller which is a little slow for graphics processing. The next upgrades from ST, the STM32H7xx, is also likely to be too slow. The solution for the next few years of production seems to be adding a graphic co-processor to the STM32F4xx.

The main problem is that it is an embedded system without PC like bus. The operating systems is a minimal real time version produced by Keil lacking all the services of Windows or Linux.

So, I am looking for a chip to mount on my boards that would interface like a memory on the parallel bus or use an SPI interface.

Does anybody know of a suitable co-processor on the market.

Thanks!

Dear SolarEagle,

Thank you for your help.

Unfortunately these links didn't provide hints to higher performance hardware for GPU usage. I already know what is available in the STM32 series since i have ran many queries before turning to this community.

I am still looking for a GPU like those used by Nvidia but on a "usable" format.

Regards,

Marco

Have you tried tweaking the performance with the software offered? Do you have a target in mind?....or just faster?

I don't know exactly what I will need a I am new to deep learning and CNN. I can only evaluate from the applications described on line and they all need more power...

We see what our cell phone can do and that is impressive but not enough for my objectives.

Since I am re-designing the control board for the next generation of product, I consider including the interface for some co-processor in case I need more power once we implement CNN and the likes.

Of course, if the integration is too complex, I will wait until a specific need.

You lost me right at the get go, why not just slap an LCD on the thing and tell it "Hello World"? Anyone with an Arduino can even do that? Surely this CPU you have can handle a few instructions and symbols in C++?

What is needed is a simpler circuit than an Arduino with its own programming and operating system.

Beside, it is for an industrial product so all the hobbyist boards are out of question.

Co-processors have specialized IOs that are designed to operate in collaboration with the main processor and share the memory bank. My problem is that I haven't found any for medium size applications. They tend to all be overkill.

I hope that some OEM has produced a "nice" chip / board that fits the medium range capacity. Maybe only few people yet know about.
