As shown in the figure, the green parts are all the v7-A architecture, and the blue ones are the v8-A architecture, basically the green supports both 32 and 64 bits. Except for A32, which only supports 32 bits. On the right side of each part, for example, the most efficient A15-A73 at the top is … Read more

Soft Cores vs Hard Cores Embedded processor hard-core FPGAs, also known as SoC FPGAs, integrate hard-core processors into the hardware design from the outset, allowing for pure hardware implementation without consuming FPGA logic resources. The hard-core processor and FPGA logic are largely independent of each other. In simple terms, SoC FPGAs combine an ARM processor … Read more

Follow Arm Technology Classroom by clicking the card below This article is authorized to be transferred from the WeChat public account Embedded Column. This article mainly shares the implementation of simple Asymmetric Multi-Processing (AMP) core-to-core communication using FreeRTOS message buffers, taking the STM32H7 (M4 and M7) dual-core processor as an example. 1. Overview The communication … Read more
Seeing that the number 9 in ARM9 is larger, do you think it is better? Seeing that a lot of information is based on S3C2410, do you think it is still quite popular now? If we could turn back time 10 years, ARM9 and S3C2410 were indeed quite popular. Why do I say this? Because … Read more

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 … Read more
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 … Read more
Arm architecture has dominated the embedded processing and computing market today, but it has come a long way over the past few decades.Starting in the 1980s, it was initially used as a home computer processor, then in the 1990s it became the foundation for mobile phone chips.Today, Arm is a strong competitor in almost every … Read more
