Many years ago, the processors were slow, and they only can compute additions and, spending some time, multiplications. Calculating division was a hard task, and no mention trigonometric operations and square roots. As low resources makes the people smarter, in…
As I said in other posts, I am FPGA designer in a company. My functions are, between others, implement the signal acquisition and apply different digital signal processing algorithms, to obtain a signal that the FPGA can use to control…
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…
In this blog I have tried to show you different tools, usually in the field of digital signal processing, so you can select the correct tools for your projects. This time we will use the tools that we have used…
Many times we need to manage low frequency signals sampled at high rates. This can be due to the need of detect edges in that signals as fast as possible, for example if we are using that signal to protect…
While we are driving on the way to our jobs, we have the 99.9% of our attention to the road, but I am sure that the other 0.1% of our attention is focus on the radio. Radio has been with…
If we are working with analog signals, is very common that we will need an analog level for set an offset if we are working with a bipolar signal, or maybe we will need an analog level to set a…
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…
This will be the first post of 2022, and I want it to be some different. Time ago I have been thinking write about how I started to use FPGA and also what I expect of them for the future.…
