About MMX and SSE instruction sets in Visual C ++

Q: seafrog: Hello, I have seen two articles you translated on MMX and SSE programming. However, they are all used in Visual Studio. NET. I want to use it in Visual C ++. the header files emmintrin. h and xmmintrin. h cannot be found on my machine. I have installed visual c ++ on my machine. Do I need to download the packages from Intel's website and decompress them before these two files are available? What package does it need to download? How can I configure MMX and SSE commands in VC?

A:Emmintrin. h and xmmintrin. h header files need to be obtained from Intel. It is best to download the Intel processor pack on its website. This pack is incompatible with vc6 Because VC is not fully compatible with the Data Type in c99. In addition to vs.net (vs.net can better support c99), I suggest using Intel compiler directly. Or you can try to solve this problem by using Microsoft Visual C ++ 6.0 Processor Pack, which can be downloaded from the Microsoft website.
