2018-02-10 Nanyi 21CTO Learning programming is to learn high-level language, that is, those designed for human computer language.However, the computer does not understand the high-level language and must be translated into binary code by the compiler before it can be run. Learning a high-level language does not mean understanding the actual running steps of a com

Chapter 4 Basic Knowledge 1.1 machine language Machine language is a collection of machine commands. The machine command is a command that can be correctly executed by a machine. The computer's machine commands are a column of binary numbers. The computer converts it into a column of high and low levels to drive the computer's electronic devices for computation. Because of the hardware design and internal s

In Embedded Assembly, the C language expression can be specified as the operand of the assembly instruction, and you do not have to worry about how to read the value of the C language expression into which register, and how to write the calculation result back to the C variable, you only need to tell the program the in

(i) Research overviewNot only can data be stored in registers, but it can also be stored in memory. This time we're going to study how to store data directly in memory in C language. As well as some of the extension issues of doing so. In addition, in the Appendix study, we also explored the implementation of cyclic and branching structures in C language.(ii) The research process1) Use the memory space dire

The words of this gentleman are not empty, so there is no need to study him? (Nonsense, of course! Otherwise, why did you write this article .) Don't worry, don't worry, let me take it easy: 1.

1. Overview An assembly language is a machine-oriented language designed for a specific computer or computer series. It consists of execution instructions and pseudoinstructions. An execution command is a symbol of a machine command. Its operation code is represented by a memory character. The address code is represented by a number, variable, and constant (??) .

Arm compilers generally support assembly language programming, C/C ++ programming, and mixed programming. This chapter introduces some basic concepts of arm program design, such as pseudo commands of arm assembly language, statement format of assembly

scenario analysis, and in the first chapter of the book there is an introduction to the mixed programming of C language assembly in GCC, and the compiler used by VxWorks is gcc!You might as well try it out, so you have the following code: /*****************gettsc-get TSC count************************************* Get the TSC (timestamp counter) count value

It must be emphasized that when programming in a 32-bit assembly language, all address offsets are 32-bit.Never use the original 16-Bit mode. For general-purpose registers, 32-bit registers such as (Exx) are added, and its
