Custom AXI IP for acceleration.

I will use this post to show you how, creating an AXI IP, we can accelerate our applications on Petalinux, or in case we use a Zynq MPSOC, we also can accelerate an application running in the RPU.

Single tone detector with Genesys ZU and RTU.

When I started to investigate about signal processing, what made me feel happier was decode a signal that, apparently, has no sense. Discrete Fourier Transform (DFT) turns something meaningless into something meaningful. That is amazing but, if we are looking for the value of one component of the...

Genesys ZU and Zynq US+.

This week I have received the big (big) sister of the Eclypse Z7, the Digilent’s Genesys ZU. This board, due to its FMC, ZMOD and PMOD is a good choice for digital signal processing applications, but first, let’s take a look to its brain, a powerful Zynq Ultrascale +.

EclypseZ7, Petalinux and signal processing at the edge.

In my last post, I said 2 things come to my mind when we talk about signal processing. One of them is FFT, and I explained you how to compute an xFFT on the Digilent’s EclypseZ7, or other Xilinx 7 series device, the other thing that I talked, was the sinc function. This function, is used, besides...

Eclypse Z7 and xFFT.

When we talk about digital signal processing, 2 things come to my mind. First one is the sinc wave, used as a cover page of a lot of books about signal processing, and the second one, is the fourier transform.

Eclypse Z7, ZMODs and SYZYGY.

Few months ago, Digilent presented their new development platforms based in Zynq and Zynq US+, with connectors compatibles with SYZYGY standard. This standard is in the middle between PMOD and FMC, with the enormous advantage that can be soldered by makers, with a solder, and some patience.

Emulating hardware with Zynq.

Due to quarantine, most of us are working from home, and seems that the way we used to work, even more when our work consist in write or develop with our laptop, will be change. When your work is computer based, for example, on web, is easy still working from home with the same benefits and limit...

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...
