Intel® Integrated Performance Primitives

VS2012 and IPP 8.

Hi,

I've install ipp and the integration with VS 2012 doesn't work....

VS Premium 2012 
Intel C++ Composer XE 2013 SP1 8.0.0.083

In VS 2012 in one project :
Project - Properties - Intel Perf Lib set to single threaded static
Project - Properties - General - Composer XE is not listed.....

left click on project - Composer - 
The only option is c++ compiler, and if I select it I got the message:
No Intel C++ compiler for platform(s) in the project(s).

Asynch Examples

Hello

I am testing the IPP Asynch examples on the new i7 4770 CPU and I observe that the speeds of the CPU and the GPU acceleration are equal. Shouldn’t I expect a speedup with the GPU accelerated implementation? Should one configure something at the beginning of the GPU accelerated implementation (like for the CPU num threads previously)? Can anybody share some of her/his experiences with the new GPU library?

Optimized RGB and RGBA Compositing

Is there anything in the IPP that will accomplish using the Alpha channel of RGBA image to overlay the RGB components onto an RGB image or to a new image?  I've taken a look at the ippiAlphaComp() functions, but they do not seem to allow mixing of C4R and C3R.

Basically looking for this:

SourceB = RGB image

SourceO = RGBA image

Memory error in IPP 8.0

Hi,

I'm working with l_ipp-samples_p_8.0.0.005, umc_video_dec_con, Linux OS. I decode my sample H.264 file: umc_video_dec_con -i test.264 -o dest_dec.yuv When I run it with Intel Inspector XE 2013 Update 9 (build 328075), I have 2 errors:

Uninitialized partial memory access umc_h264_dec_ippwrap.cpp:25; umc_h264_task_supplier.cpp:899 umc_video_dec_con

Uninitialized partial memory access umc_h264_dec_ippwrap.cpp:65; umc_h264_task_supplier.cpp:899 umc_video_dec_con

Possible problem with IPP 8.1 and VS2012?

 I just bought Intel Cluster Studio 2013 XE for Windows, I used the SN to login to Intel's website to download the latest package: Cluster Studio XE 2013 SP1 Update 1 for windows, built in Feb. 2014. 

 

Following the installation instructions, I installed all the packages here (including single and multi-threaded static libaries for IPP), the installation process itself is flawlessly, at least according to the installer.

The problem I met is (with Microsoft visual studio):

The integration with MS visual studio 2012 is bugged: IPP simply doesnt work properly:

left and right eigenvector

Hi,

I'M trying to use the ippmEigenValuesVectorsLeft_m_64f and ippmEigenValuesVectorsRight_m_64f functions.

I think there is a bug (or I missunderstand) the defintion:

A*z=λ*z for the right eigenvectors z,

zH*A=λ*zH for the left eigenvectors z,

My example:

A(2x2) = 2, -2, 1, 5

ippmEigenValuesVectorsLeft_m_64f gives λ1=3, λ2=4

and eigenvectors(2x2) = -0,89, 0.71, 0.44, -0.71

ippmEigenValuesVectorsRight_m_64f gives λ1=3, λ2=4

and eigenvectors(2x2) = -0,71, -0.44, -0.71, -0.89

FAX CED (ANS, ANSam) tone detection

Hello,

I am working on a project that requires me to detect FAX answer tone (CED) (2100Hz duration 2.6 to 4 seconds).

I created a tone using an online tone generator and fed raw PCM data to 'DetectTone' function multiple times, but it did not detect a tone. I tried initing USC_TD_Fxns with 'USC_ANSs_Fxns' and 'USC_ANSam_Fxns'.

Since this did not work, I did a loopback of the data generated by IPP 'GenerateTone' function the same way as above. I inited the tone generator with (USC_ANSam_Fxns) and generated USC_ANSam tone, with duration 10 and volume 1.
