Recreate the picture of Yamhill EM64 T and IA 32e If I have never argued with professor Jen I would never have the will to guess how to recreate picture of Yamhill EM64 T and Ia32e Yamhill is the code name of a project for ever Intel s own 64bit x86 processor EM64 T is a technology to extract the most potential capability of IA 32 making it to address up to 64TiB physical address IA32e is not a mode of Yamhill processor but the superset or extension of IA 32e in other words when ia32e enabled 32bits and 64bits codes could work seamlessly because ia32e scale up the original IA 32 by extending the width of registers and execution units extended segment descriptors and paging mechanism would also introduced with it IA32e does not make a processor turn into a real 64 bit processor but just make a 32 bit processor has the capability to do the 64 bit computing from the ground The benefits of this is that we don t have a second 64bit lised IA 32 what we need is an architecture completely designed for 64 bit computing from scratch for example Itanium or something else Janagewen on travel Preceding unsigned comment added by 42 2 159 106 Segmentation or Paging is the Essential Way for Physical Addressing Intel 8086 is the very first processor in the x86 series it has only one mode real mode And this name was later found in 80286 So segmentation had been accompanied with x86 processor since its beginning Without protection mechanism introduced segmenataion is the only way to address all possible and potential physical space Because Segmentation is found in the real mode so addresses in Segmentation tends to be real with solid link the physcial address rather than virtual address when in protected mode when paging is enabled So if it is a real x86 processor its maximum physical addressing space should be limited by its segmentation mechanism rather than paging
