作者：zyl910 　　关于获取各种CPUID信息，我之前积累了不少代码，现在决定将它们封装在一个模块中，方便代码复用。
　　其次，前面只是介绍了CPUID的一些常用功能，而Intel、AMD的手册中定义了大量的CPUID功能。所以我希望有一个程序能按照功能号顺序，依次显示所有的CPUID信息。这样就能很方便的与Intel、AMD的手册进行对照，有助于学习与理解。

一、模块设计

　　最初方案是 想将所有功能全部放在一个“ccpuid.h”头文件中，这样用起来会比较方便。
　　但是考虑到全局变量等问题，以及需要编写CCPUID类。所以最终决定按照常规做法，分解为头文件与实现文件。 　　对于原先所写的宏定义、类型定义等声明性内容，可以直接放在头文件中。
　　对于原先的simd_sse_names等常数数组，考虑到全局变量问题，觉得作为CCPUID类的静态成员会比较好（CCPUID::SseNames、CCPUID::AvxNames）。
　　对于原先的函数，__cpuid/__cpuidex作为内联函数，放在头文件中；而其他函数作为普通函数，放在实现文件中。 　　除了封装原来的代码之外，还决定增加这些功能——
1. 全部的CPUIDFIELD常数。根据Intel、AMD手册及网络上的一些资料，将目前所有的CPUIDFIELD常数均定义一遍，方便各种情况下的使用。
2. CPUID字段的描述信息。定义了CPUIDFIELDDESC结构体，然后还定义了CCPUID::CPUFDesc这个静态成员，它是CPUIDFIELDDESC结构体数组，记录了每条CPUIDFIELD常数的名称与描述文本。这样就可以通过查找表格得知CPUIDFIELD常数的描述信息。
3. 缓存的描述信息。这是为了方便使用CPUID指令的功能2是获取缓存信息。因为每一个字节代表不同的意义，所以可以使用一个256个项目的字符串指针数组来存储描述文本。（CCPUID::CacheDesc）
4. CCPUID类。拥有存储CPUID信息的能力，提供Vendor、mmx等方法，用于随时翻查CPUID信息。还设计一个cur静态方法，返回一个默认的CCPUID对象，简化代码编写。

二、测试程序

2.1 简单使用

　　最基本的用法是，定义一个CCPUID变量，然后调用RefreshAll方法刷新信息——
 CCPUID ccid;
 ccid.RefreshAll(); 　　在大多数时候，为了简化代码，可以调用cur静态方法来获得默认的CCPUID对象——
 CCPUID& ccid = CCPUID::cur(); 　　获得了CCPUID对象之后，便可以调用它的成员函数来获取基本信息——
printf("CCPUID.InfoCount: %d ", ccid.InfoCount()); printf("CCPUID.LFuncStd: %.8Xh ", ccid.LFuncStd()); printf("CCPUID.LFuncExt: %.8Xh ", ccid.LFuncExt()); printf("CCPUID.Vendor: %s ", ccid.Vendor()); //printf("CCPUID.Brand: %s ", ccid.Brand()); printf("CCPUID.BrandTrim: %s ", ccid.BrandTrim());

　　获取SIMD指令集类的信息也很方便——
printf("CCPUID.MMX: %d // hw: %d ", ccid.mmx(), ccid.hwmmx()); printf("CCPUID.SSE: %d // hw: %d ", ccid.sse(), ccid.hwsse()); for(i=1; i=i) printf(" %s ", CCPUID::SseNames[i]); } printf("SSE4A: %d ", ccid.GetField(CPUF_SSE4A)); printf("AES: %d ", ccid.GetField(CPUF_AES)); printf("PCLMULQDQ: %d ", ccid.GetField(CPUF_PCLMULQDQ)); printf("CCPUID.AVX: %d // hw: %d ", ccid.avx(), ccid.hwavx()); for(i=1; i=i) printf(" %s ", CCPUID::AvxNames[i]); } printf("F16C: %d ", ccid.GetField(CPUF_F16C)); printf("FMA: %d ", ccid.GetField(CPUF_FMA)); printf("FMA4: %d ", ccid.GetField(CPUF_FMA4)); printf("XOP: %d ", ccid.GetField(CPUF_XOP));

　　上面与前面博文中的代码差不多，只不过将全局函数变为CCPUID对象的成员函数而已，例如 simd_sse_names变为CCPUID::SseNames、getcpuidfield变为了ccid.GetField。

2.2 显示所有的CPUID信息

　　因为CCPUID类缓存了CPUID信息，而且还有CPUFDesc描述信息数组，所以编写显示所有的CPUID信息的程序十分容易。 　　我把它分为两个函数——
prtCcpuid：是外循环，对每一条CPUID信息调用prtCcpuid_Item函数。
prtCcpuid_Item：是内循环，在CCPUID::CPUFDesc数组中找到功能号相同的CPUIDFIELD子集，然后逐一输出该字段的数值、名称、描述等信息。 　　代码如下——
// 打印CPUID字段_某项. void prtCcpuid_Item(INT32 fid, INT32 fidsub, const INT32 CPUInfo[4]) { static const char* RegName[4] = { "EAX", "EBX", "ECX", "EDX" }; INT32 mask = CPUIDFIELD_MASK_FID | CPUIDFIELD_MASK_FIDSUB; INT32 cur = CPUIDFIELD_MAKE(fid, fidsub, 0, 0, 1) & mask; int i; for(i=0; i1) { printf(" %s[%2d:%2d]", RegName[reg], pos+bits-1, pos); } else { printf(" %s[ %2d]", RegName[reg], pos); } printf("=%s: 0x%X (%u)", v.szName, n, n); if (bShowDesc) { printf(" // %s", v.szDesc); } printf(" "); } } } // 打印CPUID字段. void prtCcpuid(const CCPUID& ccid) { int i; for(i=0; i0) // 最高位为0，且不是全0 { for(int k=0; k<=3; ++k) { if (j>0 || k>0) // EAX的低8位不是缓存信息 { int by = n & 0x00FF; if (by>0) { printf(" 0x%.2X: %s ", by, CCPUID::CacheDesc[by]); } } n >>= 8; } } } } } }

　　prtCcpuid函数中有两个技巧——
1. 处理规范子功能号。检查子功能号，如果是规范的子功能号，便故意设为0，根据子功能号0的字段来解析各个子功能号的信息。
2. 处理特殊功能号。对于功能0和功能80000004h，可以利用Vendor、Brand这两个成员函数。对于功能2（缓存信息），可以利用CCPUID::CacheDesc数组来解析。
