Many years ago, the processors were slow, and they only can compute additions and, spending some time, multiplications. Calculating division was a hard task, and no mention trigonometric operations and square roots. As low resources makes the people smarter, in…
As I said in other posts, I am FPGA designer in a company. My functions are, between others, implement the signal acquisition and apply different digital signal processing algorithms, to obtain a signal that the FPGA can use to control…
That FPGA are very versatile devices is something that everybody knows, and the fact that you can implement inside many different processors makes the FPGA very interesting devices for test different processors architectures. In this blog we already saw the…
There are many cases where we will need a processor inside our FPGA. In my case, soft cores are very useful when I have to implement in the FPGA a manager for an external device using high level interfaces like…
Few years ago, microprocessors manufacturers competed to get the faster processor. High speed means more tasks can be executed in the same amount of time, but also, means higher power consumption. To improve this, the voltages of the core starts…
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…
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…
Manage an ADC is something that any engineer dedicated to signal processing has to do very often. This task, in general, use to be no much complicated, unless you are using a high-speed ADC with LVDS interface or something similar,…
On the project developed on the last 2 posts, to verify the behavior of the filter, we had used the data acquired from the ILA. Data was processed on MATLAB with a script where we read the csv, and verify…
A few years ago, FPGAs were used almost exclusively for communication systems. On the other hand, DSPs are used to execute digital signal processing algorithms. The reason is the hardware components that were integrated. FPGAs, were based on flip-flops, LUTs…
