Языки описания аппаратуры, такие как VHDL и Verilog, недостаточно эффективны для решения этой проблемы при объемах программируемых микросхем в сотни тысяч логических ячеек. Прежде всего потому, что применение HLS само по себе не гарантирует качественного роста производительности.


Vivado hls fft

I am trying to compute the Fast Fourier Transform FFT of 16 parallel input data and therefore, I would like Vivado hls fft retrieve 16 output data in parallel. More specifically, if I understood correctly the datasheet, the current Xilinx FFT IP Core allows to load data one-by-one and therefore, they have to come in sequentially. Moreover, after the FFT Vivqdo is completed, data come out also sequentially. I think you could have been answered more directly.

I thank you Vivado hls fft advance. Usually, you run the IP core at a greater than or equal speed of data, so serial is quite fine. What is your data rate? Do you really receive 16 samples at the exact same hle I thank you very much for your interest. I am actually realizing an academic project aiming to improve a system by maximizing its input data rate and I can easily choose the format of my input data. I am working on a Virtex 7 platform and the target clock frequency is around MHz without parallelisation but I still desire to keep the higest possible clock frequency after parallelization.

I heard it might be possible to parallelize the output while keeping a serialized input and it seems to be an acceptable solution. Do you have any idea about how to realize that? Easiest way is to perform Vivado hls fft, it would cost you 16 complex multiplier-accumulator. This is the solution that cost Vigado less ftf, but the most DSP blocks. You can cut that in half by using a pre-adder and adding some control logic. Thank you for suggesting that path! Can you explain me a bit more where exactly do fct intend to put the convolution block?
