Intel processor identification and cpuid command (2) cpuid command

Cpuid commands have two sets of functions. The first function returns the basic information of the processor, and the second function returns the extended information of the processor. Figure 1 summarizes the basic information of the processor that can be output by the cpuid command. The output of the cpuid command is completely dependent on the content of the ea

Attention matters1. Each question can only be submitted 5 times;2. The program obtains input from standard input stdin (' Standard input ') and outputs output to standard output stdout (' Standard output ').3. Input and output can not contain any hint information;4. The compiler core of the test platform is VS2005 and JDK1.7. When using the Java answer, the class name must be "Main", do not use the Package keyword declaration, and use the data types and functions supported by VS2005 when using C

Cpuid Assembly command

Use the cpuid Assembly command (machine code: 0fh a2h, if your compiler does not support cpuid command, only emit machine code), this command can be recognized by the following CPU: More than 486 of Intel CPUs, CPU above cyrix M1, CPU above amd am486 (1) obtain the cpu oem string to determine the CPU vendor Let eax = 0 first, then call cpuid InEl CPU will return:

How to Use the cpuid command in each version of VC and 64-bit

We have discussed the use of cpuid commands (http://www.cnblogs.com/zyl910/archive/2012/05/14/dos16_getcpuid.html) in 16-bit dos real-time mode ). Nowadays, 64-bit windows is very popular. How to Use cpuid in 32/64-Bit mode? This article describes how to use the cpuid command in each version of VC and 64-bit. 1. intrinsics functions such as _

Correct understanding of the C ++ cpuid command

The C ++ programming language has a wide range of applications. Many of these functions can help us meet certain requirements and improve programming efficiency to a certain extent. Here we will introduce some application methods for the C ++ cpuid command for your convenience. Overview of basic concepts of C ++ class template Specialization Understand the basic concepts of C ++ non-type template parameters Summary of precautions for using non-typ

Obtain the CPUID, hard disk serial number, and MAC address in Linux

Article Title: Obtain the CPUID, hard disk serial number, and MAC address in Linux. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In the development of many system software, some system uniqueness information is required. Therefore, obtaining the host's CPUID, hard dis

ASM obtains the CPU serial number/CPUID, asmcpuid

ASM obtains the CPU serial number/CPUID, asmcpuid I know there are two ways to obtain the CPU serial number: ASM and WMI. If it is better, it must be the first choice for compilation. There is nothing to explain. We only embed assembly in the C #, C ++, and E languages to obtain the CPUID. First, let's take a look at, The above is C # The CPUID obtained after th

VMware Modify CPUID

Execute the WMIC CPU get processorid command under the cmd shell, but look at the cpuid of the machine, but this command shows only 2 sets of IDs, actual CPUID, 4 groupsBy changing the virtual machine configuration file. VMX implements the designation of any CPU serial number, and the CPU serial number does not revert to the original value after restarting the virtual machine. Here's how:Open the. vmx file

HW-Video acceleration in Chrome/chromium HTML5 video playback hardware acceleration

IntroductionVideo decode (e.g. YouTube playback) and encode (e.g. video chat applications) is some of the most complex compute operat Ions on the modern web. Moving these operations from software running on general-purpose CPUs to dedicated hardware blocks means lower power consu Mption, longer battery life, higher quality (e.g. HD instead of SD), and better interactive performance as the CPU is free Everything else it needs to do.design media::videodecodeaccelerator (VDA) and media::vid

Each of these network ports is a port that is registered as a net_device in the Switchdev framework. In addition, the kernel comes with a rocker driver, demonstrating an actual device-driven implementation. The entire switchdev is as follows:650) this.width=650; "src="
