Strange IPC behavior

Following discussion https://communities.intel.com/message/257079 I am creating this thread to get some help in explaining a strange behavior in the time taken by some instructions on Intel CPU.
In short, I am measuring the IPC of a program in two cases:
Case 1: when I skip 29 instructions in the control flow of the program,
Case 2: when I execute them.

Enhancing In-Vehicle-Infotainment Application Reliability and Performance using Intel® System Studio

Intel based solution is available to reduce the time and cost of developing in-vehicle technologies by providing application-ready solutions consisting of compute modules, automotive middleware and development kits. Intel® System Studio can be used in various stages of In-Vehicle-Infotainment development right from debugging BIOS in hardware layer to performance tuning of HMI layer.

  • Self-compiled GCC available for download doesn't recognize -fmpx flag

    Hi...

    I compiled the sources of GCC 4.7.2 available for download here at this Intel page. I can perfectly run the compiler, however it doesn't seem to understand the -fmpx flag: it throws me an "unrecognized command line option" error.

    Penalties in SSE4

    Hi,

    Is there any penalties with in Intel SSE4?

    Read in some document like accessing the partial register data from XMM register and from GPRs will cause some penalty.

    Is there any document to understand better on the Data transfer penalties among the SSE registers.

    Digital Security and Surveillance on 4th generation Intel® Core™ processors Using Intel® System Studio 2015

    This article presents the advantages of developing embedded digital video surveillance systems to run on 4th generation Intel® Core™ processor with Intel® HD Graphics, in combination with the Intel® System Studio 2015 software development suite. While Intel® HD Graphics is useful for developing many types of computer vision functionalities in video management software; Intel® System Studio 2015 is an embedded application development suite that is useful in developing robust digital video surveillance applications
