cpuid instruction

Brief introduction of SSE technology Intel's single instruction multi-data streaming extension (sse,streaming SIMD Extensions) technology can effectively enhance the ability of CPU floating-point operations. Visual Studio. NET 2003 provides programmatic support for the SSE instruction set, allowing users to directly use the functionality of the SSE Directive in C + + code without writing assembly code. The

Instruction Practice Development Guide in AngularJS (1), angularjs Guide Directive is the most important part of all AngularJS applications. Although AngularJS already provides a rich set of commands, you often need to create application-specific commands. This tutorial will show you how to customize commands and how to use them in real projects. At the end of this article (Part 2), I will guide you how to use the Angular command to create a simple no

Instruction basic Format: 1, the items within the 2, opcode: instruction mnemonic, such as LDR,STR, etc.; 3, cond: implementation conditions, such as eq,ne, etc.; 4, S: Whether the value of the CPSR register is affected; 5, Rd: Target register; 6, Rn: The register of the first operation number; 7, Operand2: the second operand; In an arm directive, the flexibility to use the second operand increases the ef

amount of displacement in its instruction call RET does not affect the condition code Interrupt instruction INT interrupts into overflow then interrupts Iret from interrupt return due to each interrupt vector occupying 4 bytes of unit. So the type number n specified in the interrupt instruction needs to be multiplied by 4 to get the interrupt vector of the

Schematic diagram of Java Virtual Machine 4. JVM machine Instruction Set0. Preface The Java virtual machine runs binary machine code like a real computer. java source code compiled. the class file is the binary machine code that the Java Virtual Machine can recognize. Java can identify the information and machine commands in the class file and then execute these machine commands. So how does the Java Virtual Machine run these binary machine codes? Thi

IntroductionThe 8086CPU transfer instruction is divided into the following categories:Unconditional transfer instructions (e.g., JMP)Conditional Transfer Directivesloop instructions (e.g. loop)ProcessInterrupt9.1 Operator OffsetThe operator offset is a symbol that is handled by the compiler in assembly language, and its function is to obtain the offset address of the label.9.2 JMP InstructionsJMP is unconditionally transferable, can only modify IP, an

The previous chapter describes how C is translated into assembler and how the assembler is used. But how is the assembler implemented? For example (add%eax%edx) This instruction, we know its function, how does the processor execute the instruction to get the desired result? -This is the subject of this chapter.(i) Y86 instruction set architectureTo simplify the p

DoubtsLooked up a lot of information, the introduction of the instruction name is a stroke, only said the hump form. However, when used in practice, it is often encountered that the defined instruction name does not correspond to the instruction label. The name of the instruction was very confusing. The name of the dir

The ARM7 processor has two instruction sets: 32-bit ARM instruction set, 16-bit thumb instruction set. 1> ARM Instruction set: High efficiency, high code density 2> Thumb Instruction Set: has a high code density. Note: 1. All arm instruc
