c、c++、汇编实现CPU 的性能检测 The CPUID sample provides a routine that uses the CPUID instruction to determine the capabilities of the CPU being run. The sample provides the function int _cpuid(_p_info *pinfo), which returns data about the CPU. The int return value is a bitmask of flags for major processor features. The bits that might be set are: •#define _CPU_FEATURE_MMX 0x0001 •#define _CPU_FEATURE_SSE 0x0002 •#define _CPU_FEATURE_SSE2 0x0004 •#define _CPU_FEATURE_3DNOW 0x0008

Bochs is a highly portable open source IA-32 (x86) PC emulator
written in C++, that runs on most popular platforms. It includes
emulation of the Intel x86 CPU, common I/O devices, and a custom
BIOS. Currently, Bochs can be compiled to emulate a 386, 486,
Pentium, Pentium Pro or x86-64 CPU, including optional MMX,
SSE/SSE2/SSE3 and 3DNow! instructions. Bochs is capable of running
most Operating Systems inside the emulation including Linux, DOS,
Windows 95/98 and Windows NT/2000/XP.
Bochs was written by Kevin Lawton and is currently maintained by
the Bochs project at "http://bochs.sourceforge.net".

The Netwide Assembler, NASM, is an 80x86 assembler designed for portability and modularity. It supports a range of object file formats, including Linux and NetBSD/FreeBSD a.out, ELF, COFF, Microsoft 16-bit OBJ and Win32. It will also output plain binary files. Its syntax is designed to be simple and easy to understand, similar to Intel's but less complex. It supports Pentium, P6, MMX, 3DNow!, SSE and SSE2 opcodes, and has macro capability.
