I would say, there was not much new in this. The key part of the project was the real time approach. Acquire samples, process them, find peaks, do FFTs, sum, multiply, divide. Get a float number, turn on the proper LEDs. The data was moved in C code between DMA blocks written in VHDL. Actually far away from optimized version. But it worked. IP does not belong to me and I would like to avoid technical details. The project was ended immediately when the company we worked for offered 25000€ for all IP created during the project. Very bad joke. I am still confused, because there was massive potential in this cooperation for everybody involved.
