cpuid instruction

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

: whether the CPU supports Ia MMX is very important! If you want to use the 57 new commands, check this digit first. Otherwise, you will wait for Windows to see "The program has executed illegal commands and will be shut down. (3) dedicated detection of P6 Architecture First let eax = 1 and then call cpuid If Al = 1, it is Pentium Pro or Pentium II. (4) dedicated detection of amd cpu Information First let eax = 80000001 h and then call

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

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 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

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

The arm instruction set provides two instructions to directly control the status register (psr,program State Register). The Mrs Instruction is used to transmit the value of the CPSR or SPSR to a register; In contrast, the MSR transmits the contents of a register to CPSR or SPSR. These two instructions are combined to read/write to CPSR and SPSR.Cpsr_c represents the low 8 bits in this 32-bit, which is the c
