Working with Kria SOM.

In this blog, we already talk about the kit KR260 in this post. In that post, we used the KR260 to implement an acceleration design. The cost and the power of this development board make it a very interesting board to deploy Zynq MPSOC designs. If we compare its cost, around 350$, with the cost o...

Capturing the ISM band with RTL SDR.

When I started to play with SDR devices, I didn’t realize how many signals can be captured with these devices. We are surrounded by radio signals like WIFI, Bluetooth or 4G. These signals, although we don’t know exactly how they work, we are comfortable with them, but when you connect a device li...

Configuring the PL design from the PS on Zynq MPSOC.

Since the early 90s, JTAG is the standard to program many different embedded devices like microcontrollers, processors and also FPGA. This standard is based on a serial protocol that allows the connection of different devices in a chain mode. JTAG is specially used in the debug step of a project,...

Running Ubuntu in the Microchip's Icicle Kit.

RISC-V processors are everyday more used in many different applications. This is why companies like Canonical are releasing their Linux distributions for devices based on RISC-V. One of the latest devices added to this family is the Microchip’s Icicle Kit, a development board from Microchip base...

New blog.

If you have arrived here, you will notice that some changes are made in controlpaths.com, but the most important changes are behind. Controlpaths is now based on Jekyll, which allows me to write my posts using Markdown, with all the advantages that this brings to me like code highlight and LaTeX ...

Vitis acceleration flow and the KR260.

Since a few years ago, FPGA are widely used for acceleration. In this blog, we have talked about how we can connect an FPGA to the PCI socket of our computer, and interchange data between the processor and the FPGA. SOCs, give us the chance to have in a single chip a processor (CPU) and an FPGA, ...

Running a physical model on a Speedgoat.

I have said in some posts that you can do everything with an FPGA, and although that affirmation is false, an FPGA cannot do an omelet for example, you can indeed do many things with an FPGA. Because of their parallel nature, and speed, FPGA are widely used to implement complex control algorithms...

Application Notes

[AN001] Designing from zero an IIR filter in Verilog using biquad structure and bilinear discretization.

Filtering is likely the most common DSP algorithm that any embedded engineer has to design, no matter it they are developing for an STM32, or TI DSP or, of course, en FPGA. Filtering is such important because the majority of the applications are connected to the real world, so they need to captur...

[AN002] Running subcycle average models on Speedgoat Performance System.

Materials like Silicon Carbide (SiC) or Gallium Nitride (GaN) are making our power electronics converters faster and faster. This means small inductors and capacitors that make, in most cases, the cost of the devices decrease. This also means that the control devices also have to be faster, and n...
