Windows is developed using environments such as ads codewarrir, compilers are armasm, and Linux is GNU arm, More close to the att style. In favor of Linux environment, so chose the GNU arm Assembly.Learn the plans and goals of the

The first part is the arm assembly syntax in Linux. Although it is very convenient to use C or C ++ to write programs in Linux, the Assembly 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 can download the relevant

Encryption technology can ensure that your files are stored in encrypted form, whether you want to disclose them to the Internet, back up them to the server, use a USB flash drive, or store them in a notebook. Encryption of your data means that no one else can read your data unless it is the recipient you acknowledge. This prevents information leakage. GPG (GNU Privacy Guard) GPG is short for GNU Privacy G

Under Gnu/linux, when you need to open other format files, we usually go into the directory where the file is located, double-click Open, very effective. In fact, you can open these format files, even Web pages, by command Xdg-open, as simple as opening a file. Under Gnu/linux, text files are usually opened using the command line, such as commands Gedit, more, cat, vim, less. But when you need to open othe
