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

This is what MicroCPUID do

vendor_id   : GenuineIntel
cpu family  : 6
model       : 30
stepping    : 5
model name  : Intel(R) Core(TM) CPU          Q 820  @ 1.73GHz

Why MicroCPUID display so little information?

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