This is how it looked like: ... typedef enum // IPP's List of Supported Processors & Features { ippCpuUnknown = 0x00, ippCpuPP = 0x01, // Intel(R) Pentium(R) processor ippCpuPMX = 0x02, // Pentium(R) processor with MMX(TM) technology ippCpuPPR = 0x03, // Pentium(R) Pro processor ippCpuPII = 0x04, // Pentium(R) II processor ippCpuPIII = 0x05, // Pentium(R) III processor and Pentium(R) III Xeon(R) processor ippCpuP4 = 0x06, // Pentium(R) 4 processor and Intel(R) Xeon(R) processor ippCpuP4HT = 0x07, // Pentium(R) 4 processor with HT Technology ippCpuP4HT2 = 0x08, // Pentium(R) 4 processor with Streaming SIMD Extensions 3 ippCpuCentrino = 0x09, // Intel(R) Centrino(TM) Mobile Technology ippCpuCoreSolo = 0x0a, // Intel(R) Core(TM) Solo processor ippCpuCoreDuo = 0x0b, // Intel(R) Core(TM) Duo processor ippCpuITP = 0x10, // Intel(R) Itanium(R) processor ippCpuITP2 = 0x11, // Intel(R) Itanium(R) 2 processor ippCpuEM64T = 0x20, // Intel(R) 64 Instruction Set Architecture (ISA) ippCpuC2D = 0x21, // Intel(R) Core(TM) 2 Duo processor ippCpuC2Q = 0x22, // Intel(R) Core(TM) 2 Quad processor ippCpuPenryn = 0x23, // Intel(R) Core(TM) 2 processor with Intel(R) SSE4.1 ippCpuBonnell = 0x24, // Intel(R) Atom(TM) processor ippCpuNehalem = 0x25, // Intel(R) Core(TM) i7 processor ippCpuNext = 0x26, ippCpuSSE = 0x40, // Processor supports Streaming SIMD Extensions instruction set ippCpuSSE2 = 0x41, // Processor supports Streaming SIMD Extensions 2 instruction set ippCpuSSE3 = 0x42, // Processor supports Streaming SIMD Extensions 3 instruction set ippCpuSSSE3 = 0x43, // Processor supports Supplemental Streaming SIMD Extension 3 instruction set ippCpuSSE41 = 0x44, // Processor supports Streaming SIMD Extensions 4.1 instruction set ippCpuSSE42 = 0x45, // Processor supports Streaming SIMD Extensions 4.2 instruction set ippCpuAVX = 0x46, // Processor supports Advanced Vector Extensions instruction set ippCpuAES = 0x47, // Processor supports AES New Instructions ippCpuX8664 = 0x60 // Processor supports 64 bit extension } IppCpuType; ... Can you see that CPUs and Features of CPUs are mixed? ]]> http://software.intel.com/en-us/articles/intel-integrated-performance-primitives-intel-ipp-is-there-any-function-to-detect-processor-type/#comment-69228 Mon, 09 Jan 2012 21:28:46 -0800 http://software.intel.com/en-us/articles/intel-integrated-performance-primitives-intel-ipp-is-there-any-function-to-detect-processor-type/#comment-69228
