Brief introduction: In this paper, we propose an architecture mode-interface assembler mode in interface design, it is committed to the decomposition of the interface, the interface and assembly behavior decoupling, the interface logic processing and domain logic to understand the decoupling, so that we develop GUI rich Client interface application can be from a large number of interface control management, and focus on my The development of the back

I. Advantages and disadvantages of inline compilation Because using inline assembler in Visual C + + does not require additional compilers and connectors, and can handle things that are not possible in Visual C + +, and can be used in C + + variables, it is convenient. The inline assembly is mainly used in the following situations: 1. Use assembly language to write functions; 2. Code that requires very high speed; 3. Direct access to hardware in t

I saw a post on the CSDN forum this morning http://topic.csdn.net/u/20120917/14/82f42e17-977a-4824-95bd-7b79db15d283.html: "C language embedded in the assembly, What is the point? ”One example is to insert a piece of assembler code into the C language to get the CPU's frequency, manufacturer and model://=====================================================================================/* The CPUID instruction is the assembly instruction for obtainin

A simple BIOS Program (based on ubuntu and Bochs2.2.1) written by the assembler-Linux general technology-Linux programming and kernel information. The following is a detailed description. See my blog http://blog.sina.com.cn/jhx0301 for detailed steps Today, I suddenly came up with an idea to write the BIOS. Maybe it was a whim. I read some information and decided to write a simple BIOS program. I. preparations: 1. I personally think Bochs simulation s

Data types in the MASM assembler　　Ii. types of immediate numbers in Intel compilationsIii. defining signed and unsigned integersFour, small end sequenceIn-memory data is stored in bytes, a 4-byte unsigned integer with a high position stored at a low address and a low store at a higher address.For example 0x12345678 this integer, in memory according to memory address from small to large arrangement is: 0X78 0x56 0x34 0x12V.

1. The process of the new project is unchanged, the selection of the chip, but in the new file is the. asm suffix2. Once the assembler is complete, place it in a folder and then right-click on the project to generate the hex file3. Then press the Debug button4. Step Execution (step button), you can see the changes on the right side of the PSW,R0-R7,A,B,PC, you can choose the Memory tab in the lower right corner, enter the storage space you want to see

Debug Win32 Assembler with vc6 debugger source code Using a good debugger is undoubtedly crucial to learning Win32 Assembly. I prefer the powerful debugging environment of VC rather than makefile files.Programming Environment: vc6.0 and masm32v8 The method is as follows:1. Use vc6 to create an empty project, such as test (Win32 console, Win32 application, etc ).2. copy the files in the assembly project to the directory of the new project (hello. ASM,

you're not looking at these things? Well... These things are called compilations!This is a backtracking image in Xcode that shows the assembler function in the simulator.Look at the picture above, this assembly can be divided into several parts. Each line of assembly instructions contains an opcode, which can be considered a very simple computer instruction.So what does the opcode look like? An opcode executes instructions for a simple task in the co

Comparison of 2.6.1 and Intel assembly languageWe know that Linux is a member of the Unix family, and although the history of Linux is not long, many of the things associated with it originate from UNIX. In terms of the 386 assembly language used by Linux, it also originated from UNIX. UNIX was originally developed for PDP-11, and has been ported to the VAX and 68000 series processors, and the assembly language on these processors is at/t's instruction format. When UNIX is ported to i386, it nat

The so-called conditional compilation, which is based on conditions set, enables the assembler to assemble a particular section of a program, or not to assemble a particular paragraph. In Java, for example, you might want to output some debug statements during the development phase, and the statements of these tests should not be output when the project is formally running (you might say you can use log4j, of course). For example, the following sectio

Recently looking at "Linux Kernel source code scenario analysis", author Queen Maud. At the beginning of the book, I introduced the assembler assembly with GCC and the linked list of Linux kernel data structures. Unfortunately, the book is not comprehensive enough to introduce. Because we recommend reading the following two articles. Very good.At -T assembly and GCC inline assembly: http://grid.hust.edu.cn/zyshao/Teaching_Material/OSEngineering/Chapte

This section uses the GNU debugger to check the previo

This semester to learn the assembly, on their own computer found that Win7 DOS does not support 16-bit real mode.For programming, the inability to execute a program is fatal.After collecting information on the Internet, we get a solution--using DOSBox software to executeDOSBox simple, is a DOS simulation program, support 16-bit real mode.1.
