1. Basic Concepts atpcs (arm-thumb Procedure call standard) A set of basic rules for calling between subroutines, including rules for using registers during subroutine calls, rules for using data stacks, and rules for passing parameters. With these rules, a separately compiled C language program can be called with the assembler program.C-language subroutines compiled with the C language compiler of ads satisfy user-specified atpcs types. For assembly

0 Base starts with C language. In the book see the single-chip assembly language and embedded C language comparison, more useful. 1. The main function in the embedded C program is the main program in the assembler, and the function in the embedded C program is the subroutine in the assembler program. The program runs from the main function or the main program and terminates at the last statement in the main

The concept of macro macros is found in many languages.In general, the mechanism of a macro is to replace or expanded a macro that has already been defined at the pre-compilation stage, that is, to replace the macro by its name with the contents of the macro.The macros in Rust are different!The macros in rust are also

VS2012 in the Win32 platform compile time can be very good support of assembly language embedding. Create a console application and select an empty project. After the project is established, add a. cpp file. Write the following code in the CPP file:[CPP]View PlainCopyPrint? #include using namespace std; int Add (int NUM1, int num2) { __asm { MOV eax,num1 MOV ecx,num2 Add EAX,ECX } } void Main () { inta = ADD (2,3); cout System ("pause"); }

executable file, and initializes the relevant initialization, such as Cs:ip pointing to the first assembly instruction to be executed. The program is then executed by the CPU. 3, a simple assembly language source program assume CS:CODESGNBSP;NBSP;NBSP;NBSP;NBSP;CODESG segment mov ax,0123h mov bx,0456h add ax,bx NBS P Add ax,ax mov ax,4c00h int 21h codesg ends end The code above is a simple addition operation, here are some concepts to explain.

As assembly language is closer to the hardware level than C + +, it is often possible to take the form of embedded assembly in C + + code to speed up the program in high performance requirements.In the VC can be simple through__asm{//Add assembly code here}to achieve. The following is a very simple example of the performance gap between Assembly cross-compilation and direct C + + code, with the following code and running results:#include If you are in a complex program, the difference in perform

Starting from the simplest Win32 Assembler, helloworld Write by nine days Yan Ling (jtianling) -- blog.csdn.net/vagrxie Discuss newsgroups and documents Since I started to get plug-ins, my personal goal has been very clear. I took this opportunity to re-learn Win32 compilation. I bought a book and started to learn about it because of the urgency of C ++ learning, I gave up... This is almost the same as the learning process of python in the past .....

Most computers use a 8-bit block (known as Byte byte) as the smallest addressable memory unit, rather than accessing individual bits in memory. The program treats the memory as a very large byte array called the virtual memory (virtural memories). Each byte of the memory is marked by a unique number, called its address, and the set of all possible addresses is called the virtual address space.This virtual address space is just a conceptual image, and the actual implementation is shown in chapter
