curprev 07:0007:00, 16 October 2024 Guy Harris talk contribs 19,141 bytes +490 →B6500: Indicate that words have 48 data bits and 3 tag bits (4 tag bits in later machines?), and that there are several descriptor types, with tag bits used to indicate descriptors, with references. List the various Bxxxx machines in the series, and indicate that the A-series machines were both from Burroughs and Unisys undo

curprev 02:2002:20, 16 October 2024 Ian.joyner talk contribs 18,113 bytes −423 Undid revision It is not true that B6000 was a separate or radically different product line from B5000. The architecture was the same but with some enhancements. The implementation technology might have been very different. Chatul might be thinking of the B1000 or B2/3/4000 product lines. Please provide reasoning behind the comments. undo Tag: Undo

curprev 00:3200:32, 19 April 2023 Guy Harris talk contribs 16,781 bytes +163 Again, it's not as if using paging rather than segmentation was something that first happened with x86-64; very few OSes used segmentation on IA-32 except for 1) executable space protection on processors lacking the NX bit, 2) thread-local storage, and 3) running 16-bit programs that used segmentation to expand the address space. Relegate all the x86 weirdness to the x86 section and leave it out of the lead. undo

curprev 07:3807:38, 18 April 2023 Guy Harris talk contribs 16,790 bytes +35 →x86 architecture: Many OSes started using paging with IA-32, before x86-64. Copyedit a bit. (Still needs an explanation of 1) 32-bit OSes using the segment registers for some purposes, such as making writable regions of the address space non-executable and *vice versa*, and providing thread-specific data and 2) what the stub segmentation in x86-64 does and how it's used (e.g., for thread-specific data). undo
