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...

Adding a MicroBlaze coprocessor to an edge computer.

In the industry, we can find many different applications, and most of them, especially in recent years, these applications require some kind of computing. Acquiring data on where the application is, and processing the data later in any other location, maybe an office or any kind of data center is...

Getting started with Speedgoat.

On this blog we have seen many projects where we have used FPGA, in general using development boards, unfortunately, there are not many cases where I can show you an FPGA in a real application, but this is one of these cases. The device I am talking about is a Real-Time Target Machine from Speedg...

The FPGA invasion

Let’s come back 20 years ago. FPGA are mystical devices used in exotic applications. They came from programmable PAL memories that could be used to execute simple logic operations, and not only simple but the amount of logic that they could execute was also very low. These simple devices were evo...

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...
