When I started to develop designs for FPGA, the thing that I missed from the digital signal processors is the debug capabilities. I used to debug my programs using JTAG that performs “real time” reads of the data memory, so…
When we think about radio signals, we often think that all of them are private, impossible to decode, complicated… but nothing far than reality. It is true that acquire radio signals needs some knowledge about communications but now a days,…
When I talk about Open Souce, the first that comes to my mind is GNU This operating system was developed by Linus Tourvalds and Richard Stallman in the early 90’s, then all the code was released to the community. Now,…
Sometimes I receive emails or direct messages on LinkedIn from readers asking me about where they can find documentation about DSP, FPGA or both together. Unfortunately, I didn’t find webpages where talk about how to make DSP on an FPGA,…
When we are designing an acquisition system, sometimes process the signal is not enough, there are many cases where the project requires that the value of a measurement must be shown in a user interface. This is very easy when…
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…
Digital signal processing involves many different operations. Although there are some algorithms with a high level of digitalization, they can be computed only with additions and shifts, others require specific hardware. For example, we need multiplicators to use an IIR…
When we is studying a degree related with electricity (electronics, electronics, electrical, communications, …), one of the elements which is very familiar to us is the oscilloscope. I remember when I started my electronics course (here in Spain we call…
You can do everything with an FPGA. I have used this sentence many times in my job, and most of them followed by, its all a time matter. Also, in this blog I have said many times that FPGA are…
The process to design a IIR filter is always the same. First of all we have to design the design the filter using its continuous transfer function, then, once the natural frequency of the filter, the order and the quality…
