When we look into communicating an FPGA with a computer, the first interface that we can find is UART, but this interface has several limitations in terms of speed. In order to transfer high amount of data between the CPU…
In this blog we already talk about Pynq and how it can help us to develop some applications in a easy way. Obviously, Pynq has its limitations but it still being a powerful tool with we can develop projects in…
In the previous post I have design an audio equalizer. On that design I have used 3 different FIR filters to split 3 different frequency bands in order to send them to different speakers. Very low frequencies will be sent…
Digital signal processing can be used in almost all engineering field, from seismology, to obtain the distance where an earthquake has been generated, to data science, but these areas use digital signal processing as a way to obtain the real…
Everybody knows that the processor of the moment is the RISC-V, even it is not a processor itself, the amount of the boards based on RISC-V is growing more and more. To understand the reason of that, we have to…
Digital signal processing algorithms are, in general, purely mathematical algorithms that works perfectly on our notebook or MATLAB, but in real design, the algorithm starts to return us some unexpected results. One example of that is the quantification error. While…
In this blog we have seen how to develop a FIR filter. In this post you have an example of FIR filter where the coefficients are configured though AXI4-Lite interface. The goal of that post was the implementation of a…
Several years ago, electronic designs began to feature System on a Chip (SoC) technology. This technology is an excellent choice for designs that require a higher integration or a reduction in Bill of Materials (BOM) cost. On this blog we…
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…
For developers who work with FPGA and digital signal processing, and for signal processing I mean audio signals, video signals, radio signals, … sure they have used the AXI4-Stream protocol. The AXI4-Stream protocol is used as a standard interface to…
