I am a newbie so chances are am overlooking things.

So I installed the IPP library as I wanted to do so some big number arithmetic. The "Cryptography for Intel IPP Reference Manual" that came with it lists the BigNumber class.

However I dont see any header files having any declaration/mention of it anywhere within the install folder. I dbl-checked the install to see if I had missed speciyfing any options during install time which could have installed it but nope. Neither do it I see any samples for it...

Where can I find it? what am I missing?

thx,

Hi all!

I use IPP from 6.1 version appearance. 1 week ago we installed IPP 7.1 and reconfigured our source code to be compiled with 7.1 version.

Results are very strange. Overall performance decreased more than 4 times.

Maybe 7.1 requires some special settings?

Hi all.

I have a question. The code below is image processing for median filter in real-time.

But, after median processing the image comes with a diagonal  as shown in Fig 1.

Try to solve this part, fix the below source.

But, the Image is broken. as shown in Fig.2.

So, after processing median filter,  I want to get the image without diagonal.

For reference, I was using Intel IPP 7.1.

Please ask for advice.

Thank you.

When I run this code, 7 is written to the console (SSE 2 is enabled). If I run some FFT methods and re-run initialization, I get 3295 (SSE 4.2). What can I do to get consistent results from this API?

I am using .NET 4.0 with P/Invoke signatures for all methods used below:

class Program
{
static void Main(string[] args)
{
IppCpuType cpuType = core.ippGetCpuType();
core.ippInitCpu(cpuType);
if (cpuType == IppCpuType.ippCpuAVX)
core.ippEnableCpu(cpuType);
