Hi,
In the following articles you can see a good summary of the history of FPGAs (as seen from the FPGA group on Reddit):
The 28nm AMD-Xilinx 7 series devices are used in industrial, automotive, test and measurement, aerospace and defense, and medical markets.
AMD-Xilinx has formally announced extended support for all 7 series FPGAs and adaptive SoCs through at least 2035, including the Spartan®-7 and Artix®-7 FPGAs, the entire Zynq®-7000 SoC portfolio, as well as Kintex®-7 and Virtex®-7 FPGAs. All speed and temperature grades are included.
Continue reading “AMD-Xilinx extends series-7 product lifecycle”Chapter 3 of this tutorial series on VHDL arbiters ended with the simulation of a round-robin arbiter. Here is the picture again, for reference:
Let’s take a look again at the marker placed at 670 ns. Two masters (1 and 2) are requesting the bus, but as we know, only one of them can receive it at a given moment, and in this case, it is master 2. But here happens something strange: Master 1 drops its request, even given the fact that it never received a grant signal! Although such behavior is possible, it is not common. The usual behavior of a master is to keep the request signal asserted until it receives a grant.

Continue reading “Exploring Zynq MPSoc – free book”This book introduces the Zynq® MPSoC (Multi-Processor System-on-Chip), an embedded device from Xilinx® that combines a processing system that includes Arm® Cortex®-A53 application and Arm Cortex-R5 real-time processors, alongside FPGA programmable logic.
The book covers the architecture of the device, the design tools and methods, conventional hardware/software co-design approach, and the newer software-defined methodology, as well as hardware and software development, multiprocessing, safety, security and platform management, system booting, and special features on PYNQ (a Python-based framework) and machine learning applications.
This book should serve as a useful guide for those getting starting with, and the working with Zynq MPSoC, and equally as a reference for technical managers wishing to gain familiarity with the device and its associated design methodologies.
This is the third part of a series of articles on VHDL arbiters.
In the first part, we talked about what a VHDL arbiter is.
In the second part, we saw the VHDL code for a fixed-priority VHDL arbiter.
When I talked about what a VHDL arbiter is, I gave the example of the single car we had at home, and how I had to decide who gets to use the car next Friday evening. In a typical situation, if both children ask for the car, the first thing they will account for is, who got the car the last time.
The fixed priority arbiter is the equivalent of always giving your car to the same child. It will, no doubts, create problems. If you don’t want to create problems, you will make a balanced assignment of the valued resource between the solicitors.

As published on Reddit:
An open-source raytraced game runs as software or as just gates in an FPGA, achieving up to 50x efficiency gains.
The project was featured in the embedded news site CNX-Software today. An introductory video is at https://www.youtube.com/watch?v=hn3sr3VMJQU.
