I think it could be considered as a proprietary information and the document you're looking forcould be for Internal Use Only.
If somebody would ask me to release some technical details for some algorithm "X" implemented in our software product I would tell it is based on a classic implementation and it uses SSE. I think it would be enough.
Latest version of Intel's IPP supports ~20 different CPUs, or so,and actual implementations of many algorithmsareoptimized for each CPU. For example,some algorithm "Y" is implemented with SSE2 instructions on CPU "A", and for CPU "B" isimpemented withSSE4.1, etc.
These are interesting links, but I could not find what I first asked for initially.
I understand your argumentation, but the document I'm looking for is cited in the official IPP documentation. As such it's something that a reader is led to to learn more. Now you're saying it could be somewhat confidential. If it were like you are saying, then the citation clearly does not belong into the documentation targeted at end users.
In fact I wouldn't have asked the question if the citation wouldn't have been there. But now, since it is there, I want to know.
