Hello guys i work with VHDL and C for a while (small company gotta do the SW and the HW)
We are developing a product (embedded system) and some calculus were taking too much time doing it on software, so instead using a C program to do this calculus now we are using hardware.
I developed a VHDL module responsible for doing FFT calculus that is an order of magnitude faster than the software equivalent plus it is real time by default (since it's hardware)
Now we have a SoC with a FFT hardware attached to the CPU
