Address alignment issues on ARM platforms

Preface ARM has been popular for a long time. It is unlikely that you don't know ARM when doing embedded development. Given its high performance at low power consumption, it has become the first choice for most embedded devices. However, for those who are just starting out, you may encounter some strange problems. Af

ARM--GPIO port

The s3c2440 has a total of 130 GPIO ports, divided into 9 groups, GPA ~ GPJ, controlled by registers. There are three types of registers that control the GPIO port of s3c2440, namely GPxCON, GPxDAT, and GPxUP (x=A ~ J): GPxCON: GPIO control register, which can set the input and output mode and function of the select

The connection between Arm design philosophy and efficient C language programming

1. RISC Design Concept The ARM core uses RISC architecture. RISC is a design concept whose goal is to design a simple and effective instruction set that can be executed in a single cycle at a high clock frequency. The design focus of RISC is on the complexity of the instructions executed by the hardware, because softw

Testing and analysis of 8051, ARM and DSP instruction cycles

In real-time control systems, the most important issue when selecting the indicators of a microcontroller is the calculation speed. The instruction cycle is an important indicator that reflects the computing speed. For this reason, this article analyzes and tests the instruction cycles of the three most representative
