CPUID should be called with EAX = 0 first, as this will store in the EAX register the highest EAX calling parameter (leaf) that the CPU implements. To obtain extended function information CPUID should be called with the most significant bit of EAX set. To determine the highest extended function calling parameter, call CPUID with EAX = 80000000h.
A system monitor displaying system resources usage. A system monitor is a hardware or software component used to monitor system resources and performance in a computer system. [1]
CPUID model numbers are 30h-3Fh. AMD Bulldozer Family 15h – the successor to 10h/K10. Bulldozer is designed for processors in the 10 to 220 W category, implementing XOP, FMA4 and CVT16 instruction sets. Orochi was the first design which implemented it. For Bulldozer, CPUID model numbers are 00h and 01h.
The instructions below are those enabled by the BMI bit in CPUID. Intel officially considers LZCNT as part of BMI, but advertises LZCNT support using the ABM CPUID feature flag. [3] BMI1 is available in AMD's Jaguar, [5] Piledriver [6] and newer processors, and in Intel's Haswell [7] and newer processors.
Intel Haswell Core i7-4771 CPU, sitting atop its original packaging that contains an OEM fan-cooled heatsink. This generational list of Intel processors attempts to present all of Intel's processors from the 4-bit 4004 (1971) to the present high-end offerings.
With the introduction of the Pentium processor, Intel provided a pair of instructions (RDMSR and WRMSR) to access current and future "model-specific registers", as well as the CPUID instruction to determine which features are present on a particular model. Many of these registers have proven useful enough to be retained.
An x86-64 processor acts identically to an IA-32 processor when running in real mode or protected mode, which are supported modes when the processor is not in long mode.. A bit in the CPUID extended attributes field informs programs in real or protected modes if the processor can go to long mode, which allows a program to detect an x86-64 processor.
