Many people who never have used a Hardware Description Language (HDL), either Verilog or VHDL, thinks that these languages are weird. Actually, being able to generate code that is executed in parallel make the head of software developers explode, yes…
In this blog we already talk about Litex in this post, and also we used Litex to run Linux in a SoC in this post. If we remember the flow, the steps are very simple. We need to execute some…
That FPGA are very versatile devices is something that everybody knows, and the fact that you can implement inside many different processors makes the FPGA very interesting devices for test different processors architectures. In this blog we already saw the…
In the last post we talked about digital control loops. In short, we talked about the elements that we can find in digital, or analog, control loops. The first of them is an element to acquire the difference between the…
There are many cases where we will need a processor inside our FPGA. In my case, soft cores are very useful when I have to implement in the FPGA a manager for an external device using high level interfaces like…
Few weeks ago Dialog Semiconductor announced a new series of FPGAs named as ForgeFPGA. The highlight of these new devices are not a high processing power, the highest speed or the big they are, the main highlights of these devices…
When I am working in a design for an FPGA, which involves the acquisition of any signal, I usually have to design a filter before using that signal in the control loop, or a protection. If the use of this…
In this blog we already talk about Pynq and how it can help us to develop some applications in a easy way. Obviously, Pynq has its limitations but it still being a powerful tool with we can develop projects in…
Digital signal processing algorithms are, in general, purely mathematical algorithms that works perfectly on our notebook or MATLAB, but in real design, the algorithm starts to return us some unexpected results. One example of that is the quantification error. While…
In this blog we have seen how to develop a FIR filter. In this post you have an example of FIR filter where the coefficients are configured though AXI4-Lite interface. The goal of that post was the implementation of a…
