The Ultimate Integration: AXIOM Perfectly Combines Arduino, ARM, and FPGA

After two years of development, the AXIOM board has finally been launched. Initially, AXIOM was supported by seven different enterprises from Europe, including three research institutions/universities: the University of Siena, the Barcelona Supercomputing Center, and Fourth, along with four tech companies: SECo, Vimar, Evidence, and Herta Security.

The AXIOM board is the first to combine three different product lines: Arduino, ARM processors, and FPGA. In the design of AXIOM, the best components were chosen to achieve maximum real-time hardware acceleration with

Common Commands for ARM Development Boards

1、reboot means to restart.

2、source makes the modified files take effect immediately, avoiding the problem of having to restart for the changes to take effect. For example, if we modify /etc/profile, the changes will not take effect immediately. In this case, we can enter source /etc/profile to apply the changes.

There will be more updates in the future.

3、chmod -R 777 /home/edu/practice sets all file permissions in the practice folder to 777.

4、Compress a single file: gzip

Understanding ARM Cortex-M4 and Cortex-M0+ Interrupt Priority and Nested Preemption Issues

Sitting on the high-speed train from Shanghai to Beijing, the long journey really makes one feel bored (I couldn't get a direct train, so I can only go slowly, stopping at every station. It's ridiculous that in the high-speed train era, it still is like this. It reminds me of the time in college when I took a green train home

Introducing the New Zynq Z-7000S Series with Single ARM Core

Today, Xilinx announces a new product line and three latest devices in the Zynq-7000 SoC and Zynq UltraScale+ MPSoC families!
The new product line is called the Zynq Z-7000S series, with three new devices: Zynq Z-7007S, Zynq Z-7012S, and Zynq Z-7014S. The Zynq Z-7000S devices are specifically designed for smaller embedded designs, making them smaller and slightly slower than other members of the Zynq 7000 SoC series — but this slowness is relative, as these devices still offer the high-performance advantages
