Physical Address Extension - Wikipedia, the free encyclopedia (256 words)
PAE is provided by Intel Pentium Pro and above CPUs (including all Pentium-series processors except the original Pentium and the Pentium MMX), as well as by some compatible processors such as those from AMD.
The CPUID flag PAE is assigned for the purpose of identifying CPUs with this capability.
The operating system uses PAE to map this 32 bit address space onto the 64 gigabytes of total memory, and the map can be and usually is different for each process.
The Old New Thing : Myth: PAE increases the virtual address space beyond 4GB (1171 words)
PAE increases the amount of physical memory that can be addressed by the processor, but that is unrelated to virtual address space.
PAE increases the physical address space (the address space that the CPU can use to access the memory chips on your computer) from 32 bits to 36 on a Pentium 2, for a theoretical maximum physical memory capacity of 64GB.
With PAE enabled, the page table and page directory entries double in size (to accomodate the additional bits in the page frame), which significantly increases the amount of memory required for page tables and page directories (since each page table describes only half as much memory as it used to).
