# MicroCPUID

MicroCPUID is a assembly language (GNU Assembly / GAS) toy project. It detect and display CPU information. Just like `cat /proc/cpuinfo`.

# Demo

## This is what `cat /proc/cpuinfo` do

    vendor_id       : GenuineIntel

    cpu family      : 6

    model           : 30

    model name      : Intel(R) Core(TM) CPU          Q 820  @ 1.73GHz

    stepping        : 5

    microcode       : 0x3

    cpu MHz         : 1728.931

    cache size      : 8192 KB

    physical id     : 0

    siblings        : 8

    core id         : 2

    cpu cores       : 4

    apicid          : 5

    initial apicid  : 5

    fpu             : yes

    fpu_exception   : yes

    cpuid level     : 11

    wp              : yes

    address sizes   : 36 bits physical, 48 bits virtual

## Why MicroCPUID display so little information?

This is author's one-day work, don't have much functions :)
