Detailed Description

Check CPU features (hardware capabilities).

The example below shows how to check or get CPU capabilities.

#include <visp3/core/vpCPUFeatures.h>
 
#ifdef ENABLE_VISP_NAMESPACE
using namespace VISP_NAMESPACE_NAME;
#endif
 
int main()
{
  std::cout << "checkSSE2: " << vpCPUFeatures::checkSSE2() << std::endl;
  std::cout << "CPU info: " << vpCPUFeatures::printCPUInfo() << std::endl;
  return 0;
}
