With PAE, the page table entry of the x86 architecture is enlarged from 32 to 64 bits. This allows more room for the physical page address, or "page frame number" field, in the page table entry. In the initial implementations of PAE the page frame number field was expanded from 20 to 24 bits.
Intel's second generation of 32-bit x86 processors, introduced built-in floating point unit (FPU), 8 KB on-chip L1 cache, and pipelining. Faster per MHz than the 386. Small number of new instructions. P5 original Pentium microprocessors, first x86 processor with super-scalar architecture and branch prediction. P6
The page-directory entry with PS set to 0 behaves as without PSE. If newer PSE-36 capability is available on the CPU, as checked using the CPUID instruction, then 4 more bits, in addition to normal 10 bits, are used inside a page-directory entry pointing to a large page. This allows a large page to be located in 36-bit address space.
x86-64 (also known as x64, x86_64, AMD64, and Intel 64) [note 1] is a 64-bit extension of the x86 instruction set architecture first announced in 1999. It introduces two new operating modes: 64-bit mode and compatibility mode, along with a new four-level paging mechanism.
Process–architecture–optimization is a development model for central processing units (CPUs) that Intel adopted in 2016. Under this three-phase (three-year) model, every microprocessor die shrink is followed by a microarchitecture change and then by one or more optimizations.
The Carrizo mobile APUs were launched in 2015 based on Excavator x86 cores and featuring Heterogeneous System Architecture for integrated task sharing between CPUs and GPUs, which allows a GPU to perform compute functions, which is claimed provide greater performance increases than shrinking the feature size alone.
KQEMU was a Linux kernel module, also written by Fabrice Bellard, which notably sped up emulation of x86 or x86-64 guests on platforms with the same CPU architecture. This worked by running user mode code (and optionally some kernel code) directly on the host computer's CPU, and by using processor and peripheral emulation only for kernel-mode ...
The P6 microarchitecture is the sixth-generation Intel x86 microarchitecture, implemented by the Pentium Pro microprocessor that was introduced in November 1995. It is frequently referred to as i686. [2]
