If you are a student of electronic communication or are engaged in embedded electronic communication work engineer, assistant engineer, intern, handyman, I think you have a complex fear of the assembly, and even this fear is the University of learning "microcomputer technology" began. But for the author's superficial work experience, it seems that if you can master or step back and understand the assembly, then you can enjoy the fun as a hardware programmer at the bottom. Imagine using the assem

Arm and realviewEmbedded debugging of arm realview With the development of embedded applications, especially in the field of digital communication and network, it puts forward higher requirements on processor performance. To adapt to this situation, there have been many multi-core structured processors, such as two or more arm or DSP processors. At the same time,

, the power that needs to be multiplied or divided by 2 can be done by moving left or right n bits. In fact, multiplication can be replaced by any integer by shift and addition. The method of adding and shifting in ARM 7 can be completed by one command, and the execution time is less than the multiplication command. For example, I = I × 5 can be replaced by I = (I Multiplication is used to replace multiplication: A 32 × 8 Multiplier is built in the

Here we will not care about the details. Let's just talk about why ARM and X86 are not comparable. To clarify this question, first of all, we need to understand what architecture is. Many people have mentioned that the architecture is different, but what does the architecture mean?

Part 1 arm assembly syntax in Linux Although it is convenient to use C or C ++ to write programs in Linux, the assembler source program is used for the most basic initialization of the system, such as initializing the stack pointer, setting the page table, and operating the arm coprocessor. After initialization, you can jump to C code execution. Note that the GNU assembler follows att's Assembly syntax and

Apche and SQLite have a lot of information on the Internet, but PHP for ARM-Linux is rare. it took a lot of time to install PHP on the ARM platform. so I will post the building process here, hopin

Article Title: create a cross-compiling environment for arm-linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Cross-compilation environment Cross-compilation is an important technology in the embedded development process. Its main feature is that the program code executed on a machine is not compiled and gener
