如何以编程方式确定处理器类型?

在Windows系统上,您可以获得环境变量处理器体系结构。这是一篇介绍可以返回值的msdn文章。

PROCESSOR_ARCHITECTURE=AMD64
PROCESSOR_ARCHITECTURE=IA64
PROCESSOR_ARCHITECTURE=x86

vbscript,检查处理器的体系结构环境变量:

Set oShell = CreateObject("WScript.Shell")
Set oEnv = oShell.Environment("System")
Select Case LCase(oEnv("PROCESSOR_ARCHITECTURE"))
  Case "x86"
    ' x86
  Case "amd64"
    ' amd64
  Case "ia64"
    ' ia64
  Case Else
    ' other
End Select

vbscript,使用wmi:

Const PROCESSOR_ARCHITECTURE_X86  = 0
Const PROCESSOR_ARCHITECTURE_IA64 = 6
Const PROCESSOR_ARCHITECTURE_X64  = 9

strComputer = "."

Set oWMIService = GetObject("winmgmts:" & _
    "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")

Set colProcessors = oWMIService.ExecQuery("SELECT * FROM Win32_Processor")

For Each oProcessor In colProcessors
  Select Case oProcessor.Architecture
    Case PROCESSOR_ARCHITECTURE_X86
      ' x86
    Case PROCESSOR_ARCHITECTURE_X64
      ' x64
    Case PROCESSOR_ARCHITECTURE_IA64
      ' ia64
    Case Else
      ' other
  End Select
Next

C中:

using System;
using Microsoft.Win32;

  class Class1
  {
    static void Main(string[] args)
    {
      RegistryKey RegKey = Registry.LocalMachine;
      RegKey = RegKey.OpenSubKey("HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\0");
      Object cpuSpeed = RegKey.GetValue("~MHz");
      Object cpuType  = RegKey.GetValue("VendorIdentifier");
      Console.WriteLine("You have a {0} running at {1} MHz.",cpuType,cpuSpeed);
    }
  }

cat/proc/cpuinfo目录

除了安装在主机上的处理器之外,通常比底层处理器更重要的是操作系统运行的模式。

检查“uname-p”(或uname(2))的输出

英特尔采用AMD的64位指令扩展,所以“x86_64”值意味着你运行的是Intel或AMD 64位处理器,否则你运行的是常规的x86 ISA。

cpu-z是你想要的程序,它会告诉你你拥有哪个处理器,它支持什么扩展

在爪哇,你不需要知道。;)
