compiler's own function library, with-NOSTDLIB allows the compiler linker to select the function library that I write in my program.After you set up the stack in the assembly startup code, use the method (bl cfunction) to invoke the function cfunction in C language, such as the main function in the MCU (BL main). 5, the use of C language to access registers of t
OK, so, the bare-metal program does not have the support of the operating system, want to use C language, you can only use assembly language to manually configure the C language needs of the environment, sounds very tall, in fact, need to do is very simple: specifying the value of the stack pointer is good .
"In-depth understanding of computer Systems" Chapter III-Machine-level representation of the program. The author first explains the relationship between the assembly code and the machine code, expounds the function of the assembly link, then starts from the machine language IA32, describes how to store the data, how to access the data, how to complete the operati
I have learned assembly language before, but I forgot about it. I only remember mov, add, and so on.
Recently I have read an assembly language to solve the tower's problem.ProgramAnd found a big difference between a compilation and C.

Java-implemented Hack language assembly compiler-the sub-device part
I recently read computer system elements and read some basic things. I found that it would be nice to read this book before the university course compilation. Although some of it is difficult, it is still possible to browse it. After reading this article, you will know how to use this compilatio

For beginners, many of the commands in the compendium are too complex to be studied for a long time and can not write a beautiful procedure, which hinders our interest in learning the compilation, and many people give up on this. So my personal view of the compilation, not necessarily to write programs
As long as the rational use, C can still achieve unexpected results. Many friends complain that C efficiency is much worse than the Assembly, in fact, if the compiler principle of Keil C has a more in-depth understanding, it is possible to use the appropriate syntax, so that the generated C code to achieve optimization. Even though this may seem unlikely, there are some simple principles to follow: 1. Use the unsigned data structure as much as possibl

工欲善其事, its prerequisite. Assembly language is our learning, interface principle, the principle of microcomputer composition, such as the basis of a number of interesting courses. Unfortunately, however, people who have just come into contact with the Assembly always feel that it is difficult, good trouble, a lot, a good abuse of heart, a good brain abuse. So, Beh

Assembly language programming, the 32-bit system should not have any problems, but under the 64-bit system, there will be some different places. Some program samples also compile errors or execute errors.The system used by the blogger is CentOS v6.4 x64. This article mainly solves the 32-bit assembler how to assemble and connect in 64-bit environment, but does not discuss how to design 64-bit

The assembly language is the read/write version of the cpu binary command. We will have a separate chapter later to describe the assembler.Statement. Readers who have never been familiar with assembly languages may be confused when reading this book.
Most MIPS
For starters, many of the commands in the compendium are too complex, often for long periods of time, to write a beautiful program that hinders our interest in learning a compilation, and many people give up. My personal view is to learn the assembly, not necessarily write the program, write the program is really not the strength of the Assembly, we might as well play debug, sometimes crack out a little sof
assembly language, using registers
This book has already talked about why we use variables-because we store data when we program. We've also learned that in assembly language, we store data in registers and memory spaces.Let's explore how registers and memory spaces ar
Read Wang Shuang's "Assembly language second Edition" has been almost two months, the first few chapters written are some good understanding, so the speed slightly faster, to the middle, need to use the knowledge before the digestion, so some slightly slower. The middle section is the language core of the assembly, so
Learn the knowledge you should know before compiling
1. What tools and procedures are needed for compiling and where to download.
At this stage, it is sufficient for the assembler to need only two procedures.Masm.exe,link.exe. The former is the compiler, the latter is the link program. In addition, to verify and debug the program, you need a program Debug.exe, which is provided by Windows itself.
After downloading both, put it in a directory (any directory can), considering that many command
