DMA, Petalinux and the ZUBoard-1CG

Zynq MPSOC are complex device. Complex because its Processing System (PS) is based on a heterogeneous multi-core consisting of a dual or quad ARM Cortex-A53 and a dual ARM Cortex-R5. In addition, those four or six cores are surrounded by an FPGA or Peripheral Logic (PL). But they are also complex...

Simulating DSP algorithms using Verilog.

When you think about DSP algorithms, sure you think of applications such as MATLAB, Octave or Python. In the same way, when you think about simulating HDL, to your head comes words like Verilog or VHDL, but, what happens when we mix these worlds? When we have to simulate a DSP algorithm, implemen...

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 ...
