Does Intel Software Development Emulator support SSE3 instructi

Hi Sergey,

Windows and linux might be different here. On linux we compile SDE asking the compiler to insert SSE3 instructions. On windows, we only use SSE2 as a target.

In theory, SDE could run on a P4 without SSE3 and emulate the SSE3 instructions. I wrote SDE partly because I had PIIIs and had to handle P4 binaries withe SSE3, but that was a long time ago now.

I was not aware there were P4's without SSE3. SDE is built upon Pin and pin has some P4-requirements but your chip has the required features for Pin (CX8, FXSR, CMOV, SSE2).

I guess you tried it and it did not work? on Linux?

Regards,

Mark

[SergeyK] I didn't try yet. I simply wanted to get some information ifSSE3 could be supported by
SDEon Windows XP SP3?

Could you verify ifSSE3 emulationis supported andworking?

Best regards,
Sergey

It will take me a few days to find and get access to a P4 running windows. Hopefully it is easy enough for you to download SDE and try it yourself. Should work.

[SergeyK] I can't follow that path. I'd like to know in advanceif it supports SSE3. If it does than I
could schedule some time for all the rest tests.

Mark,

The SDE is not a new software product and it should have some docswith a list of supported features.
Also, you worked on the project and had, or maybe still have,full access to thesource codes. Could you
simply verify ifthe SDEsupports SSE3?

SDE supports emulation of SSE3.

On windows the SDE program itself uses SSE2 instructions.

On linux, the SDE program actually uses SSE3 occasionally.

We generally tell people that they need a P4 host to run it, but in the linux case, the P4 host would have to have SSE3.
