In previous articles, we often mentioned Armv8-A. So what exactly is Armv8-A? This question can be simple or complex. Today, let’s take some time to briefly study it. As we all know, ARM is a company that designs and licenses processors and corresponding IPs (such as interconnect buses, interrupt controllers, image processors, etc.). Currently, its … Read more
ver0.2 Introduction Previously, we introduced the core content of the General Interrupt Controller (GIC), an important component in the ARM architecture. Through a series of preceding articles, we elaborated on the system architecture of GIC, core components, interrupt types, interrupt signal routing mechanisms, state machine management, interrupt priorities, and other fundamental concepts. We believe that … Read more
Detailed Explanation of NEON Instructions Optimization The third season of ARM64 Architecture and Programming has updated its 28th lesson. This time, Uncle Ben will introduce the usage and optimization of NEON instructions. In some scenarios, NEON instructions can achieve performance improvements of over 10 times, such as in matrix operations, image processing, and artificial intelligence. … Read more
The ARM Cortex-M series is a low-power, high-efficiency processor architecture launched by ARM, mainly used in embedded systems, especially in Internet of Things (IoT) devices, smart homes, sensors, wearables, and more. The design goal of the Cortex-M series processors is to provide low power consumption and a simple architecture to support real-time operations while maintaining … Read more
After the chip is powered on and reset, the first program executed is referred to as Bootrom loader within the chip. This part of the program is hardcoded into the internal ROM space of the chip during the manufacturing process, has read-only attributes, and cannot be modified during actual use. The intellectual property rights of … Read more

STM32CubeMX Download and Installation Basic Introduction: STM32CubeMX is a graphical tool for 32-bit ARM Cortex STM32 microcontrollers. It allows for very simple configuration of STM32 microcontrollers and microprocessors, generating initialization C code, and can also generate parts of the Linux device tree for Arm Cortex-M or Arm Cortex-A cores through step-by-step operations. It is part … Read more
Former RISC-V developers face a challenge: the code density of the RISC-V instruction set for deeply embedded processors lags behind existing ARM Cortex-M tools. However, many new products released by SEGGER are changing this situation, such as the recently released SEGGER Linker, which can reduce the code size of RISC-V by 15%. SEGGER’s Runtime Library … Read more
