(The technology for 2D graphics processing has actually matured since the era of the NES; what the 6502 could do, the Cortex-M can naturally handle as well.) 【Introduction】 In our previous article “What is an Embedded System (Part 2) – The Deposition Model”, we mentioned: Current computer technology is approximately 20 years ahead of embedded … Read more
Click the card below to follow Arm Technology Academy This article is selected from the Jishu column “Arm Selection” and will list some information related to Arm v7, Arm v8, and Arm v9 architectures that people usually do not pay much attention to. 1. Although Arm v7 products are still frequently seen in the market … Read more
ARM processors are at the core of current mobile computing, embedded systems, and IoT devices. The ARM processor family is vast and is divided into three main core series based on application scenarios and performance requirements: Cortex-A (high-performance application processors), Cortex-R (high real-time processors), and Cortex-M (low-power microcontrollers). The following is a detailed analysis from … Read more
Introduction The author has been involved in embedded software development for nearly five years, primarily using microcontrollers from the ARM Cortex-M series. During these five years, thanks to the existence of C language compilers, I have been able to develop without delving into assembly language. However, it seems I have missed out on some aspects … Read more
Scan to FollowLearn Embedded Together, let’s learn and grow together We know that STM32 microcontrollers are an organic combination of ST’s peripherals and various Cortex cores from ARM.ST has produced many microcontrollers based on different Cortex-M cores. I found a comparison table of different Cortex-M core characteristics on the ARM website, and I would like … Read more
Using J-Link Debugging Visual Studio Code is a free source code editor launched by Microsoft. With plugins, it can achieve GDB + J-Link + GDBServer debugging for embedded systems in VSCode. In this article, we will introduce how to add debugging capabilities to Cortex core microcontrollers using J-Link. The example uses SEGGER’s emPower v2.0 evaluation … Read more

1. Introduction The Cortex-M processor series is based on the M-Profile architecture, providing low latency and high determinism for deep embedded systems. Our latest generation Cortex-M processor is the Cortex-M55. The Cortex-M55 is the first processor based on the Armv8.1-M architecture, featuring vector processing extensions with Arm Helium technology. The Cortex-M55 brings higher levels of … Read more
Click the blue text above Follow us! Microcontrollers (MCUs) in embedded systems are like the air traffic control systems of a busy airport. With modern MCU product lines, designers can add new features without increasing costs or reduce costs while maintaining existing feature sets, all while developing scalable software that can be reused in future … Read more
