Looking forward for a way to extract a particular word with 'like' clause from a field already populated.
For example, I have a filed holding dataset like
Intel 8175
Intel 3145
Intel 2178
AMD 2149
AMD 1200
I need an output to be extract as Intel Only.
Expected Output
Intel
Intel
Intel
AMD
AMD
I found the way with below logic in calculated filed
ifelse(
locate(processor, 'Intel') <> 0, 'Intel',
locate(processor, 'AMD') <> 0, 'AMD',
'Others'
)

You know, haswell is the codename for a processor microarchitecture developed by Intel as the "fourth-generation core" successor to the Ivy Bridge microarchitecture.1 Intel officially announced CPUs based on this microarchitecture... More
But, I want to know how to show's up my CPU if haswell or not by using the PowerShell in windows?
in this case i have a script to to that, but it maybe not legal for everyone:
$cpuname = (Get-CimInstance CIM_Processor).Name
$splcpuall = #($cpuname -csplit "")
$splcpu = $splcpuall[20]
$ishaswell = if ($splcpu -gt 3){
Write-Output "Haswell"
}
Identifying a CPU needs some digging and regular maintenance for new CPU models is needed too. Your best bet is to use some existing tool that provides CPU information. For example, CPU-Z is nice a tool.
The problem is that CPUs don't contain human readable name strings. What they contain is a CPUID, a hex code that must be looked up and interpreted as model name. Hashwell's ID is 0x0306C3, Broadwell's is 0x0306D4 and so on.
Digging up the CPUID can be done via WMI. On a Broadwell box:
(gwmi win32_processor).ProcessorId
BFEBFBFF000306D4
The result is a string combination that contains stuff in addition to the CPU ID. This needs to be parsed to identify the CPU ID part and then the matched name must be looked up from somewhere.
I want to list out the CPU Core / Processes in the system. When I have used select DeviceID from Win32_Processor, I got CPU0 as result; But I am expecting result as "CPU0,CPU1,CPU2,CPU3" since there are multiple cores. Is there any other one liner available for finding out this?
Thanking you...
I know this is old , but for others searching , Win32_Processor it contains, NumberOfCores and NumberOfLogicalProcessors
The 3rd parameter of VirtualProtect can use flags as follow:
PAGE_EXECUTE
PAGE_NOACCESS
PAGE_READWRITE
PAGE_READONLY
...
At the first I think VirtualProtect may achieve it by using PTE's flag. But when I read the structure of PTE, I cannot find the flag in PTE which record this function's 3rd parameter.
The PTE's structure as follow:
Sorry i cannot post images (for don't have 10 reputation! ), you can find it from Google.
I want to find where the Windows record the protection flag of a virtual memory page, Is not PTE？
After read some material, I Noticed that when a PTE is invalid, the meaning of PTE's fields have changed! And then have 5-bits for protection flag.
The available ProtectionFlags are a super-set of what an Intel processor supports. Keep in mind that Windows was written to run on a variety of processors, it once supported MIPS, Itanium, Alpha and PowerPC as well. A mere footnote today, AMD/Intel won by a landslide with ARM popular on mobile devices.
An Intel processor has pretty limited support for the page protection attributes. A page table entry has:
bit 1 for (R/W), a 1 allows write access, a 0 only allows read access
bit 2 for (U/S), user/supervisory, not relevant to user mode code
bit 63 for (XD), eXecute Disabled. A late addition to AMD cores, originally marketed as "Enhanced Virus Protection", adopted by Intel. All processors you'll find today support it.
So the kernel maps the protection flags like this:
PAGE_NOACCESS: the page simply won't be mapped to RAM
PAGE_READONLY: R/W = 0, XD = 1
PAGE_READWRITE: R/W = 1, XD = 1
PAGE_EXECUTE: R/W = 0, XD = 0
I need to use unique computer id for the purpose of software licensing. I decided to use CPU Flags. On MSVC they are retrived with function __cpuid, and on gcc version 4.3 and up with the function __get_cpuid. I get an integer out of these functions which is sort of a bit array with the purpose to be used as unique ID.
What I'm not sure whether the CPU flags retrieved with the above functions can ever change? Can those flags be programmatically changed by the user? If not by regular application maybe through BIOS?
Thank you.
No, an end user cannot change them because each of the commands you listed is essentially a wrapper for an actual processor opcode cpuid that is provided in Intel (and Intel-clone) chips.
So this information is 'burned' into the silicon. No user can change it.
The following resources might be helpful:
1) Wikipedia's article on CPUID
2) Code guru article (2 pages) on accessing processor info using a call to CPUID
3) Table listing many processors by stepping, family, and model numbers
OK after some testing I can confirm that the flags from the 2nd byte of Info Type 1 are changing. So I will stick with Stepping ID,Model,Family and Processor Type values only.
Title pretty much explains it all. I need to get some hardware information such as CPU info, and total RAM with VB6. Ideally, it would return something like this for the CPU:
Intel Core 2 Quad Q8500 2.66 GHz
and for the RAM something simple like an integer for the amount of MB the computer has total.
in plain C, if interested:
#include <intrin.h>
int cpuInfo[4] = {-1};
char CPUBrandString[0x40];
memset(CPUBrandString, 0, sizeof(CPUBrandString));
__cpuid(cpuInfo, 0x80000002);
memcpy(CPUBrandString, cpuInfo, sizeof(cpuInfo));
__cpuid(cpuInfo, 0x80000003);
memcpy(CPUBrandString + 16, cpuInfo, sizeof(cpuInfo));
__cpuid(cpuInfo, 0x80000004);
memcpy(CPUBrandString + 32, cpuInfo, sizeof(cpuInfo));
You could use WMI to get this information:
http://msdn.microsoft.com/en-us/library/aa394084(v=VS.85).aspx
This information is also available in the registry (if WMI isn't to your liking):
HKLM/HARDWARE/DESCRIPTION/System/CentralProcessor
NOTE: Registry keys and locations may change. The WMI API is designed as a more stable source for this kind of information.
RAM - GetPhysicallyInstalledSystemMemory (GlobalMemoryStatusEx on earlier versions)
CPU - GetSystemInfo (not in the desired friendly form, I'm afraid). There is a very extensive discussion of more detailed CPU info retrieval here.
