Memory Segmentation - History

History

The Burroughs Corporation B5000 computer was one of the first to implement segmentation, and "perhaps the first commercial computer to provide virtual memory" based on segmentation. The later B6500 computer also implemented segmentation; a version of its architecture is still in use today on the Unisys ClearPath Libra servers.

The GE-645 computer, a modification of the GE-635 with segmentation and paging support added, was designed in 1964 to support Multics.

The Intel iAPX 432, begun in 1975, attempted to implement a true segmented architecture with memory protection on a microprocessor.

Prime, Stratus, Apollo, IBM System/38, and IBM AS/400 computers use memory segmentation.

Famous quotes containing the word history:

    In nature, all is useful, all is beautiful. It is therefore beautiful, because it is alive, moving, reproductive; it is therefore useful, because it is symmetrical and fair. Beauty will not come at the call of a legislature, nor will it repeat in England or America its history in Greece. It will come, as always, unannounced, and spring up between the feet of brave and earnest men.
    Ralph Waldo Emerson (1803–1882)

    Books of natural history aim commonly to be hasty schedules, or inventories of God’s property, by some clerk. They do not in the least teach the divine view of nature, but the popular view, or rather the popular method of studying nature, and make haste to conduct the persevering pupil only into that dilemma where the professors always dwell.
    Henry David Thoreau (1817–1862)

    There is a constant in the average American imagination and taste, for which the past must be preserved and celebrated in full-scale authentic copy; a philosophy of immortality as duplication. It dominates the relation with the self, with the past, not infrequently with the present, always with History and, even, with the European tradition.
    Umberto Eco (b. 1932)
