How To Find Number of processors Present in the CPU ?
How to Find Number of Cores Present in the CPU ?
Is any possiblity to find Number Cores and Number of Processors ? (Is any difference ) ?
|
|
|
|
|
Try GetSystemInfo[^]

I love work. It gives me something to do between weekends.

fine.
GetSystemInfo is giving number of processor is 2 for Pentium D. But I have only one processor but 2 cores.
Is there any way to find number processor and number of cores.?

I guess you could use GetLogicalProcessorInformation[^] on Windows Vista and later versions.

So There is no way for Windows XP . is it ?
|

Guess not. Even the System Control Panel in XP lists it as separate processors.
But I guess it shouldn't matter to a program whether is two processors or two cores.
The documentation says that it is available on Windows XP Professional x64 Edition.

good. How CPU-z software is telling core is 2 process is 1 on Windows XP ?
( CPU-Z)[^]

I'm not really sure how that works.
But I have a thought.
The GetProcessAffinityMask[^] function returns a system affinity mask which represents the processors configured on the system. Perhaps this will give you the answer.

No, and it shouldn't really be a surprise. When Windows XP was designed (2001, remember!), multi-core processors (the whole idea of multiple independent processing units of one piece of silicon) hadn't been thought of, so Windows XP didn't include support for multi-core.
Adding support may sound easy at first glance, but it cuts across many different parts of the system, so isn't easy to do.

ok fine. Is there anyway to find number of processor and number of cores using any freeware library.
I want to use it from windows 2000 onwards.
Give a good solution

You can use the cpuid assembly instruction to get this information, it will require some assembly knowledge. I wrote the following functions a few years ago, you may want to check that they return the correct values.
__inline BOOL IsHyperThreaded()
{
BOOL bHyperthread = 0;
__asm
{
xor eax, eax
cpuid
cmp eax, 1
jb end
xor eax, eax
inc eax
cpuid
test edx, 0x10000000
jz end
mov dword ptr [bHyperthread], 1
end:
}
return bHyperthread;
}
__inline unsigned int PhysicalCores()
{
unsigned int cores = 1;
__asm
{
xor eax, eax
cpuid
cmp eax, 4
jb end
mov eax, 4
xor ecx, ecx
cpuid
shr eax, 26
and eax, 0x1F
add eax, 1
mov dword ptr [cores], eax
end:
}
return cores;
}
__inline unsigned int CpuCores()
{
unsigned int cores = 0;
__asm
{
xor eax, eax
cpuid
cmp eax, 4
jl single
mov eax, 4
xor ecx, ecx
cpuid
mov cores, eax
jmp multi
single:
xor eax, eax
multi:
}
return (unsigned int)((cores & 0xFC000000) >> 26)+1;
}
__inline unsigned int LogicalCores()
{
unsigned int cores = 1;
__asm
{
xor eax, eax
cpuid
cmp eax, 1
jb end
xor eax, eax
inc eax
cpuid
test edx, 0x10000000
jz end
mov eax, ebx
and eax, 0x00FF0000
shr eax, 16
mov cores, eax
end:
}
return cores;
}
My code will not work on the MSVC 64 bit compiler, if you are creating a 64 bit application then you will need to use the CPUID intrinsics[^]

dear sir/madam,
i m doing a project on " embedded matlab "
I have to convert matlab functions to C so i need c code of imresize(image resize) matlab function
Please forward me C codes . or guide me what I can do ?
kindly waiting for the reply

Follow the steps mentioned below.
1.read the forum guide lines first.
2.specify your problem very clearly.
3.if nobody answers you, it means that,
a>people who know the answer are not in the forum right now or
b>your question is not proper and understandable.
4.if it is not answered, then reposting your question multiple times would no way be helpful to you.
5. in this case, instead of reposting, try to put your question in a more elaborated way, such that you may get atleat clues to proceed further.
6.please delete the multiple posts. and retain only one. that will help you better.
hope you know how to delete and edit your posts. if not ask it here, i will guide you.
--------------------------------------------
Suggestion to the members:
Please prefix your main thread subject with [SOLVED] if it is solved.
thanks.
chandu.

What you really meant to say was "I have to convert matlab functions to C so i need to learn how to write c code from matlab function source code". The .m files for imrotate and imresize are included with Matlab. They are quite well documented and Matlab code isn't all that different from C.
In addition, you could use Google to search for something like "convert matlab code to c" - that's more likely to yield something of use than spamming CodeProject forums with ill thought out questions like you've been doing.

I have installed the eVC4.0, But it can't start up
with message"Microsoft eMbedded Visual C++ has discovered no CE platform SDK
installed on the desktop. Please install at least one CE platform SDK before
launching Microsoft eMbedded Visual C++."
How can I do?
Thanks.
To accomplish great things, we must not only act, but also dream;
not only plan, but also believe.
