CPUID指令是intel IA32架构下获得CPU信息的汇编指令，可以得到CPU类型，型号，制造商信息，商标信息，序列号，缓存等一系列CPU相关的东西。

比如生成查询CPU的制造商信息(Vender ID String)的代码：

{

char cVID[13]; // 字符串，用来存储制造商信息

memset(cVID, 0, 13); // 把数组清0

Executecpuid(0); // 执行cpuid指令，使用输入参数 eax = 0

memcpy(cVID, &m_ebx, 4); // 复制前四个字符到数组

memcpy(cVID+4, &m_edx, 4); // 复制中间四个字符到数组

memcpy(cVID+8, &m_ecx, 4); // 复制最后四个字符到数组

return string(cVID); // 以string的形式返回

}

android的Cpu信息是存在/sys/devices/system/cpu中的，在目录中，我们可以看到存在多个文件，一个文件就是一核Cpu的信息。上面写有cpu0，cpu1，cup3诸如此类的文件夹。

要获得它是几核的Cpu，只要读取一下那个cpu目录下有几个cpu+数字的文件夹就可以了。

/

Gets the number of cores available in this device, across all processors

Requires: Ability to peruse the filesystem at "/sys/devices/system/cpu"

@return The number of cores, or 1 if failed to get result

/

private int getNumCores() {

//Private Class to display only CPU devices in the directory listing

class CpuFilter implements FileFilter {

@Override

public boolean accept(File pathname) {

//Check if filename is "cpu", followed by a single digit number

if(Patternmatches("cpu[0-9]", pathnamegetName())) {

return true;

}

return false;

}

}

try {

//Get directory containing CPU info

File dir = new File("/sys/devices/system/cpu/");

//Filter to only list the devices we care about

File[] files = dirlistFiles(new CpuFilter());

//Return the number of cores (virtual CPU devices)

return fileslength;

} catch(Exception e) {

//Default to return 1 core

return 1;

}

}
