Access Violation Issue in ippiCrossCorrValid_NormLevel_32f_C1R

Jump to solution
Hi, We are using "ippiCrossCorrValid_NormLevel_32f_C1R" to find out cross correlation in our application running in Windows 7 64bit machine. The application is getting crashed after calling function "ippiCrossCorrValid_NormLevel_32f_C1R". We have did initial analysis of the crash dump and below are the details. The IPP version we are using is 6.1. We would need help to proceed further on narrowing down the issue. And we also want to know if it is a existing issue with IPPAPI?

Unfortunately we don't have a prototype that repro this crash, as the crash is intermittent and not happens always. Please let us know any more details that I can provide. Thanks in Advance!

Hi Sundar,

ippiCrossCorrValid_NormLevel_32f_C1R has been deprecated from later releases, you may need to use a replacing function in the newer version. There could be changes in IPP APIs and performance from different versions. For your concern 2, you may check this link https://software.intel.com/en-us/forums/intel-integrated-performance-primitives/topic/392804 and see if it feasible for your application. Without a reproducible code, it is hard to pinpoint the issue especially when it intermittent. Thanks!

Hi Sandar,

I noticed your IPP version is very old. If possible, could you upgrade to the latest IPP 2017 that just released this month and see if the problem still exist? You can download the community license version that is free here https://software.intel.com/en-us/articles/free-ipsxe-tools-and-libraries. Thanks!

Thanks Shaojuan for the quick reply! Agree with you completely. In our application we have heavily used ipp 6.1 in several places. Moving to latest IPP would require us to do a complete regression & baseline testing. If we get a confirmation\rootcause that the issue is because of old ipp libraries, then I would take it up further with our team on moving to latest IPP. Things of concern 1. Will moving to latest IPP cause baseline shifts in the results from IPPAPI calls? 2. Or else can I use latest IPP only to replace 'ippiCrossCorrValid_NormLevel_32f_C1R' functions and the rest will continue to use old IPP. But all of the IPPAPI calls we are using are in a single project. Will it not give a conflict as our project is linked to ipp libraries? or how to handle it separately. Please let know your suggestions. Thanks, Sundar
