  1. @[email protected] I don't have an exact expectation of speed, since I'm merely doing that to learn and to get a sense of what developing for an FPGA looks like. Your answer kind of helps in with that respect! Doing the brute force convolution is an intermediate goal, but the end-goal of this first project is to do fft-based convolution, since it uses less operations (I implemented a 0-latency convolution using ffts on a CPU, in C++, now I'm trying to see what it takes to do it in hardware). I guess I'll start with very simple things first like making leds blink Olivier
  2. @[email protected] I guess the memory controller needs to read 8 times from the memory bus before delivering the content (hence the 20 cycles from request to response), and maybe I could do some pre-fetching stuff to hide this latency ... If the MIG runs at 82Mhz (which makes sense since it is roughly the memory bus frequency divided by 8 ), is it possible to have a slower clock for the MIG and a faster one for the rest of the design?
  3. Hi @xc6lx45, thanks for your replies! My concern was about burning the sticker due to FPGA heat, not burning the FPGA itself. But thanks for the link! I finally just removed the sticker. I asked the question on stackoverflow regarding brute-force convolution a few days ago (just before buying the board actually): https://electronics.stackexchange.com/questions/406295/brute-force-convolution-reverb-in-fpga and someone answered with a back of the envelope calculation, where external RAM is used instead of block RAM, but in the calculation the speed of the RAM bus was not taken into acc
  4. Hello! I'm a FPGA newbie, I just purchased an Arty A7 from Amazon (the 35T version and received the 100T version - lucky me !!) and will be trying to run an audio convolution reverb on it... Well, at least that's the goal, first I'll try to power it on I guess I had a question regarding the sticker that's on top of the FPGA chip: I assume I should remove it, in case it gets hot, but didn't see any instruction to do that anywhere, is there a documentation I've missed? Cheers, Olivier
