cpuid instruction

scratchpad and requires multiple instructions to complete, so, from a performance consideration, do not use this type of instruction in the inner layer loop. (R0: = R1: = r2: = R3: = *p)._mm_loadh_pi and _MM_LOADL_PI are respectively used to load from a combination of two parameter high-bottom bytes. Specific reference manuals._mm_loadr_ps indicates that loading in _MM_LOAD_PS reverse order requires more than one

This article mainly introduces the instructions in AngularJS (2). For more information, see instructions in AngularJS (1, how to isolate the scope of an instruction. The second part will continue with the previous article. First, we will see how to access the attributes of the parent scope from inside the instruction while using the isolated scope. Next, we will discuss how to select the correct scope for t

Why do I need to introduce the instruction formatIn the learning and application of Linux, it is often necessary to enter commands in command line mode. Many books directly introduce the application of various directives, and do not speak the format of these instructions, causing many beginners not to understand these instructions very well, so this article focuses on the linux instruction format . Two Linu

For this question, the assembly language uses the method to deal with. (1) The size of the data to be processed is indicated by the register name.For example:In the following instruction, the register indicates that the instruction is a word operation:MOV ax,1MOV bx,ds:[0]MOV Ds,axMOV Ds:[0],axInc AXAdd ax,1000 In the following instruction, the register indicat

ANGULARJS directives Angularjs expands HTML by using a new attribute called a directive. Angularjs adds functionality to the application with built-in instructions. Angularjs allows you to customize your instructions. ANGULARJS directives The ANGULARJS directive is an extended HTML attribute with a prefix ng-. The ng-app instruction Initializes a ANGULARJS application. The ng-init instruction initial

Machine language We just need to focus on a few concepts: 1. The machine language instruction has the operation code (OP) and the address code two parts to compose|_____________op_______________|__d__|__w__| |_____________op_______________|__s__|__w__| In most opcode, some bits are often used to indicate certain information:As in the structure of the picture: W=1 when the word to operateManipulating bytes when w=0 The D value is valid in the dual

Will be uploaded I wrote a new book, "Write Your Own CPU" (not yet published), today is the 23rd, I try to four weekly6.4Test ProgramThis section will verify that the mobile operation instructions added to the Openmips processor are implemented correctly with a test program as follows, corresponding to the book with the CD code\chapter6\asmtest The Inst_rom in the directory .

After midnight can't sleep, keep a record of the problems that were encountered at work yesterday. A recursive instruction was written for the needs of the project. This thing actually caused Chrome to feign death. Looks so serious, even forced to quit is not good for me to restart the computer. A brief introduction to the background: The first is a tree-like data structure, about this: { id:xx, children:{ id:yy, children:{...

The ONBUILD directive can add triggers for mirroring. The parameter is any one of the dockerfile directives.When we add the Onbuild directive to a dockerfile file, the directive does not have a substantial impact on the use of the dockerfile to build the image (for example, a mirror).But when we write a new Dockerfile file to build a mirror based on a mirror (such as a B-mirror), the onbuild instruction in the Dockerfile file that constructs the A-mir

Original link: http://blog.csdn.net/jx_kingwei/article/details/367312#pragma pre-processing instruction detailedIn all pre-processing directives, the #pragma directive may be the most complex, and its role is to set the state of the compiler or to instruct the compiler to complete certain actions.#pragma指令对每个编译器给出了一个方法, given the unique characteristics of the host or operating system, while maintaining full compatibility with the C and C + + languages

Compile the SIMD Instruction Program on Linux (1) Add _ MMX __, _ SSE _ predefinitions during G ++ compilation; (2) When GCC is linked-March = pentium4-mmmx-MSSE-m3dnow (3) including header files: xintrinsic. h If you use eclipse for development, pay attention to the settings. IA-32 intel architecture instructions are mainly divided into the following categories: General X87 FPU MMX technology SSE/sse2/sse3 extensions MMX/SSE class extens

Solution to zlib compilation failure in Visual Studio 2005) Recently, I need to read and write PNG files. I tried the experiment according to the previous method, but I found that zlib 1.2.3 cannot be compiled. Error message: Inffas32.asm (594): Error a2070: Invalid instruction operandsInffas32.asm (596): Error a2070: Invalid instruction operandsInffas32.asm (610): Error a2070: Invalid

.-Depending on the functionality, the JSP contains three types of directives: page instruction, the pages directive, the include directive, which contains the instruction, and the taglib instruction, the tag Library directive. Regardless of the type of instruction, the syntax format used is as follows:650) this.width=6

1.8086 Transfer Instruction Classification: Unconditional Jump instruction: JMP Conditional Transfer directives: Loop command: Loop Procedure (function equivalent to C) Interrupt () The operator offset is a compiler-processed symbol in assembly language, and his function is to get the offset address of the label Start:mov ax,offset start; equivalent to mov ax,0 JMP unconditionally jumps, can only modify

Now in the study of the Assembly, it feels very interesting. , I will write down the learning things, as a later can learn notes ~ The loop instruction is in the form of a loop designator, which takes two steps when the CPU executes the Loop command 1: (CX) = (CX)-1 2: Determine the value in CX, not zero to go to the label to execute, if zero, then execute down From the description above, we can see the results of the execution of the impact loop

As we all know, the JVM used to be interpreted in the past, but later in the history of the revision also added to the implementation of the compilation. So in general the JVM is comprised of interpretation execution and compilation execution. This part does not belong to the scope of the JVM, has been compiled, most of them are lexical analysis and the like, there will be time to add.At the same time, we all know that now broadly divided into two instructio
