Libcpuid  Crack Activation [32|64bit] (Updated 2022)
This article will teach how to use CPUID and RDTSC instruction to read information about your processor. There are three different CPUID instruction that will allow you to read information about your current CPU: CPUID, IDT and RDTSC.
CPUID
In order to perform a CPUID instruction, we’ll use an assembly example. We start the instruction with a small piece of data (e.g. 000000000010) and we follow that with a instruction that specifies the part of the instruction set we want to examine. After that, the machine will perform that instruction in order to read the specified bits and store them in the stack. What follows is a list of instructions that is needed to perform a CPUID, as documented by Intel.
CPUID Example:
mov eax, 10h
cpuid
mov ebx, 0Ah
If you want to check the following instructions, use the following assembly code:
.386
.model flat, stdcall
option casemap:none
_cpuid
mov eax, 10h
cpuid
mov ebx, 0Ah
ret
Using the example provided above, it will display the following:
.286
.model flat, stdcall
option casemap:none
eax ebx ecx edx eip cs csz dw dwt dd ch idtr
off ebp eax cs seg ds ss es fs gs
0 00000000 0010 0200 0000 C03601 0001 0000 0000
0 00000000 0010 0200 0000 C03601 0001 0000 0000
mov eax, 10h
cpuid
mov ebx, 0Ah
ret
IDT
In order to perform an IDT instruction, we’ll use an assembly example. We start the instruction with a small piece of data (e.g. 000000000010) and we follow that with a instruction that specifies the part of the instruction set we want to examine. After that, the machine will perform that instruction in order to read the specified bits and store them in the stack. What follows is a list of instructions that is needed to perform an IDT, as documented by Intel.
IDT Example:
mov eax, 10h
cpuid
mov ebx, 0Ah
If you want to check the following instructions, use the following assembly code:
.386
.model flat, stdcall
option cas

libcpuid is a C API for obtaining the most up to date CPU information and converting it into human-readable strings. The output of libcpuid is more extensive than that of the CPUID instruction in Intel® x86® or AMD64 processor hardware.
CPUID and RDTSC are proprietary instructions added in both x86 and AMD64 chips. Unfortunately, the meaning of the data is not publicly documented. The Intel x86 CPUID instructions give more specifics on CPU features, while AMD64 CPUID gives more on instruction sets.
libcpuid is a drop-in replacement for the Windows* API routines GetCPUID, GetFeatureFlags, and GetCPUNumber. In many cases, the results from those routines are not correct, as they only show what was decided on by Intel, AMD, and OS vendors; it gives no information on the vendor's code, or other issues. libcpuid is the only program that lets you obtain detailed CPU information beyond that of CPUID, and there is no reliable way to convert the data into human-readable text.
libcpuid is developed with a focus on speed. It generates all the results in 2-4 CPU cycles (vs. CPUID's 2-9), and it also uses significantly fewer system calls and system calls in comparison to other programs.
