, 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

Some people think that Ubuntu's ARM route (supporting ARM servers) is "Gambling ". This is a bad word. Why? As we all know, CPU (CPU) is the heart of a computer, and the number of transistor particles determines its "energy consumption. However, simply pursuing the reduction of the number of transistor particles is not the fundamental solution to the problem. If there are only several hundred transistors in

In the case of the ARM architecture, qemu provides a convenient, if slow, environment in which development can be done
