The Linux kernel has a subsystem called "cpufreq", tunable by power-scheme and command line, devoted to the control of the operating frequency and voltage of a CPU. Linux runs on Intel, AMD, and other makes of CPU. [13] [14] Newer version Windows 10 and Linux kernel support Intel Speed Shift Technology.
Processor Control Region (PCR) is a Windows kernel mode data structure that contains information about the current processor. It can be accessed via the fs segment register on x86 versions, or the gs segment register on x64 versions respectively.
For example, executing CPUID instruction with the EAX register set to '1' on x86 CPUs will result in values being placed in other registers that show the CPU's stepping level. Stepping identifiers commonly comprise a letter followed by a number, for example B2. Usually, the letter indicates the revision level of a CPU's base layers and the ...
Montage Jintide CPUs can be distinguished from the Intel Xeon CPU models they're based on by the presence of the substring Montage in the brand string of the Montage CPUs (e.g. Montage Jintide C2460 [159] and Intel Xeon Platinum 8160 [160] - both of which identify themselves as GenuineIntel Family 6 Model 55h Stepping 4 - can be distinguished ...
In the mid-1990s, a facility for supplying new microcode was initially referred to as the Pentium Pro BIOS Update Feature. [18] [19] It was intended that user-mode applications should make a BIOS interrupt call to supply a new "BIOS Update Data Block", which the BIOS would partially validate and save to nonvolatile BIOS memory; this could be supplied to the installed processors on next boot.
Instruction stepping or single cycle originally referred to the technique of stopping the processor clock and manually advancing it one cycle at a time. For this to be possible, three things are required: A control that allows the clock to be stopped (e.g. a "Stop" button).
The contents of registers and memory locations can be examined; if they are correct, the system can be told to go on and execute the next instruction. The Intel 8086 trap flag and type-1 interrupt response make it quite easy to implement a single-step feature in an 8086-based system. If the trap flag is set, the 8086 will automatically do a ...
CPU Sim has the following features: allows the creation of a CPU (a virtual one), including the registers, RAM, microinstructions, and machine instructions; allows the creation, editing, and execution of assembly language programs for the simulated CPU; allows stepping forward and backward through the execution of assembly language programs.
