C++ wrapper for Intel Integrated Performance Primitives(IPP)

C++ wrapper for Intel Integrated Performance Primitives(IPP)

Naming Standard

Support Features

• Automatic tranlate C++ navitve type to Ipp types

  std::is_same(ipp::get<int8_t>::type, Ipp8s);
  std::is_same(ipp::get::type, Ipp8s); //int8_t and char are not always the same
  std::is_same(ipp::get<uint8_t>::type, Ipp8u);
  std::is_same(ipp::get<std::complex >::type, Ipp32fc);

• Automatic function dispath depend on parameter type

  uint8_t *buf1 = ipp::malloc<uint8_t>(1024);
  uint8_t *buf2 = ipp::malloc<uint8_t>(1024);
  ipp::and_const(buf1, uint8_t(0x3), buf2, 1023); //same as ippsAndC_8u(...)

  unsigned int *buf1 = ipp::malloc(1024);
  unsigned int *buf2 = ipp::malloc(1024);
  ipp::and_const(buf1, unsigned int(0x3), buf2, 1023); //same as ippsAndC_32u(...)

• Extend some original IPP function to support more types

  int8_t *buf1 = ipp::malloc<int8_t>(1024); int8_t *buf2 = ipp::malloc<int8_t>(1024); ipp::and_const(buf1, int8_t(0x3), buf2, 1023); //actually, ippsAndC_8s(...) is not supported

• Re-write some context based IPP function as C++ class to make it easy to use

  ipp::rand_gauss gas(0, 0.1, 0);
  float *buf = ipp::malloc(1024);
  gas.generate(buf, 1024);

  typedef ipp::win win;
  win w(win::HAMMING, 1024);
  w.mul(src, dst, 1024);
