Intel intrinsics support for Atom cloverview processor

I have an application which was designed for Sandbridge processors using SSE to AVX, now I want the same application to run on Atom Processors.

I was recently browsing net for intrinsic support for Atom cloverview processors. Every where it mentions it support upto SSE3.

But that means it supports just upto SSE3 or Supplementary SSE3 is included in SSE3.

In Intel Atom architecture manual it says that all Atom processors Support Single-instruction multiple-data extensions up to SSE3 and SSSE3.

Can somebody give me some clarity on the above, as I developing an application and I am not sure whether to include SSSE3 in my application.

If Intel Atom support SSSE3, that will ease a lot of my pain

Thanks in advance.

Solution

  • Cloverview, aka atom-z2760 supports SSSE3

    See the datasheet from intel http://www.intel.com/content/www/us/en/processors/atom/atom-z2760-datasheet.html

    Search for SSSE3 and it says in section 1.4 under Processor Core

    Intel® Streaming SIMD Extensions 2 and 3 (SSE2 and SSE3) and Supplemental Streaming SIMD Extensions 3 (SSSE3) support
