Radar processing on board Red Pitaya

Radar processing on board Red PitayaA good tone when running new technologies is the demonstration of the work "Hello world". For FPGA /CPLD solutions, this human interface that is indigestible to them is replaced with another greeting - a friendly flashing LED. We'll raise the bar a little higher and show how the FPGA + ARM bundle can be used in more complex applications - radar processing.
 
Farewell to the cabinets
 
For experiments, choose Zynq on board Red Pitaya. The board has two outputs (DAC) and two inputs (ADC), with digitization at a serious frequency of 30 MHz (in fact, it is possible more, but this frequency is very ...

Habits in the service of the developer

The first steps in the career are over. You can already safely wear a sweater, beard and work remotely.
 
 
Friends are jealously called IT people rock stars, but you know something that had to go through and how much more to do. While the magic pill of success is not invented, choose the right habits. They are good friends with working efficiency.

Self-development and laziness


 

Self-development


 
No matter how many diplomas you receive, do not stop learning. It's hard and boring, but the thirst for knowledge will not let you get behind the progress.

Why 2 extruders in a 3D printer?

Good afternoon everyone!
 
 
In this article, we would like to talk about a question that plagues many customers when choosing a 3D printer with 2 extruders. Namely, which is better? What is more stable? Which 3D printer to choose? Why do some 3D printers with two extruders cost much less, and what is the difference between them?
 
 

A bit of theory


 
 
First of all, we understand that under the seal of 2 extruders (or 2-component printing) we understand the possibility of printing 2 materials such as PLA (base material) and PVA (a temporary support material being removed chemically, with water ...[/h]

PCIe bus: do physical restrictions only affect the transmission speed?

PCIe bus: do physical restrictions only affect the transmission speed?I'll start from afar. Last winter, I happened to make a USB device with a core located in the FPGA. Of course, I really wanted to check the real bandwidth of this bus. After all, in the controller - there's too much to do. You can always say that there is a delay, or there. In the case of FPGAs, I see a block pumping data, so he told me that there is data in it. But I showed that everything was processed, and I'm ready to receive a new portion (in this case, it already receives data in the second buffer of the same endpoint). Great, we put the readiness from the first bar and see what happens when ...
