On last post, we had designed a filter with filter designer tool from MATLAB. After verify the filter on MATLAB and Simulink, we have to generate the HDL and verify the implementation using FPGA-in-the-Loop, and later, verify the filter on…
If I say “a software for engineering”, most of you probably think on MATLAB. I don’t know if exist any engineering field which have not a package on MATLAB, and obviously, digital signal processing and FPGA design is not one…
After a few post dedicated exclusively to the FPGA, on this post I going to talk about a technique that can help us to improve the ADC resolution. To study this technique, we will use as a example the ADC…
When we need a FIR filter, in general, or at least in my case, we already have a FIR filter HDL, where we only need to change the filter order to the application needs, in most cases this configuration can…
On the last post, we talk about the using of DMA to send data between PL and PS on SOC or MPSOC devices. The example that I proposed, was a kind of FFT compute accelerator, where a signal stored on…
It’s September, most of you will come back to work, others don’t remember what is that of holidays, and others, luckiest people, will start your holidays soon. I am in the first group, so I have to back to work,…
When I started to investigate about signal processing, what made me feel happier was decode a signal that, apparently, has no sense. Discrete Fourier Transform (DFT) turns something meaningless into something meaningful. That is amazing but, if we are looking…
In my last post, I said 2 things come to my mind when we talk about signal processing. One of them is FFT, and I explained you how to compute an xFFT on the Digilent’s EclypseZ7, or other Xilinx 7…
When we talk about digital signal processing, 2 things come to my mind. First one is the sinc wave, used as a cover page of a lot of books about signal processing, and the second one, is the fourier transform.…
