如何在vc6中使用SSE指令?

[POWERPIGGY]

本人做图象处理，由于算法时间过长，想用SSE改写。
有什么办法可以在VC6下使用SSE？
谢谢!

就是内联汇编指令,CSDN的文档中有一篇"在Visual C++中使用内联汇编"
键入关键字"内联"可以搜索到.

是可以使用内联汇编，但好象不支持SSE的指令
另外DB是什么呢？谢谢

很简单，用_emit

The _emit Pseudoinstruction

The _emit pseudoinstruction is similar to the DB directive of MASM. You use _emit to define a single immediate byte at the current location in the current text segment. However, _emit can define only one byte at a time, and it can only define bytes in the text segment. It uses the same syntax as the INT instruction.

The following fragment places the given bytes into the code:

#define randasm __asm _emit 0x4A __asm _emit 0x43 __asm _emit 0x4B
.
.
.
__asm {
randasm
}

[fatyee]

__asm
{
...
}
you may enter your SSE code within the two {}

至少db可以吧

.386
.model plat stdcall
.option casemap:none

.886!!!!!!!!

推荐1998年电子工业出版的〈图形程序开发指南〉一书，或许对你帮助。

也不用,你可以先装sp5,然后还有一个让vc6支持sse的文件名字叫vcpp5.exe你到google搜索一下就找到了!好像装上就可以用了

The Visual C++ 6.0 Processor Pack provides intrinsic support for enhanced instruction sets supported by Intel and Advanced Micro Devices (AMD) processors. The instructions sets supported are Intel's Pentium III new instruction sets (Streaming SIMD Extensions [SSE]) and Intel's Pentium 4 new instruction sets (Streaming SIMD Extensions 2 [SSE2]) as well as AMD's 3DNow! Instruction sets.

This Processor Pack is recommended only for Visual C++ users who are interested in using the new instruction sets.

db byte, byte...
byte串就是机器码.必须自己手工编码.如果使用Intel C++编译器,可以直接调用函数来实现MMX、SSE和SSE2。
