Hi. I have STM32F769i-disco board and i want to execute DFSDM audiorecord example in my board.I have some trouble when executing the DFSDM_audiorecord examples which exists in STM32F769i-eval Board. But i compile it but it doesn't playback..what ...

Hello. I want to know does stm32 cortex m7 series has TPU (tensor processing unit) for hardware acceleration. I heard that TPU has a systolic array which is a network of processors that are responsible for performing computations and passing the resu...

I use x-cube-ai 6.0 version & stm32h747i-disco board.By clicking on the [Advanced Settings] button, i use external flash memory for the weights and it works well.However, when [Use external RAM] button & copy weight to RAM , there's some problem and ...

Hello, I have a STM32F746G-DISCO which has a microcontroller with 1 Mbytes of Flash memory and 340 Kbytes of RAM. However, I would need more space for my bigger Keras models. I have seen examples of code in the new function pack FP-AI-VISION1 which ...

What I have checked through the user manual UM2526 and FP-AI-VISION1 examples is that I am using X-cube-ai version 6.0.0 for the 32bit floating point model (the model data type I am currently using), so I want to read data from external SDRAM in ord...

Hmm.. I think i revised correctly. but it doesn't work as well. It's little bit difficult for me porting the example on my board. Compile is Ok. In debugging, stuck in 879 lines.

I see that stm32 cortex-M7 core doesn't have TPU unit and also much less ALU & MACs than GPU. So it can't be fast when using parallel computations. But I can't understand why cycles/ MACC is 6~10 when using 32b floating point datatypes even though c...

Thank you for answer. The manuals are vast. If you don't mind, can you tell me where to look ?

Yjang.1 · 2021-03-18

Thank you for answer. I understand using internal SRAM is faster than using external SDRAM for intermediate inference computing. UM2611(3.2.4.5, page: 24) document said that "In order to speed up the inference, it is possible for the user to set fla...

Does Stm32F769i-disco DFSDM_audiorecord examples available?

[X-cube-AI] Does stm32 F/H arm coretex-M7 series hardware has TPU(tensor processing unit) for hardware accelation ?

[x-cube-ai] Advanced settings button (Use external RAM & Copy weight to RAM) doesn't work (using STM32H747i-disco board) for cube-mx validate on target option

Are there any easier examples or tutorials for loading the pre-trained model to external memory?

[X-cube-AI] How could i use the external QSPI & SDRAM in order to speed up the inference ?
