DEC Alpha - Memory

Memory

The Alpha has a 64-bit linear virtual address space with no memory segmentation. Implementations can implement a smaller virtual address space with a minimum size of 43 bits. Although the unused bits were not implemented in hardware such as TLBs, the architecture required implementations to check if they are zero to ensure software compatibility with implementations that implemented a larger or the full virtual address space.

Famous quotes containing the word memory:

    A man is the prisoner of his power. A topical memory makes him an almanac; a talent for debate, disputant; skill to get money makes him a miser, that is, a beggar. Culture reduces these inflammations by invoking the aid of other powers against the dominant talent, and by appealing to the rank of powers. It watches success.
    Ralph Waldo Emerson (1803–1882)

    Always get rid of theory private object in this way: assume that it constantly changes, but that you do not notice the change because your memory constantly deceives you.
    Ludwig Wittgenstein (1889–1951)

    Remember thee?
    Ay, thou poor ghost, whiles memory holds a seat
    In this distracted globe. Remember thee?
    Yea, from the table of my memory
    I’ll wipe away all trivial fond records,
    All saws of books, all forms, all pressures past
    That youth and observation copied there,
    And thy commandment all alone shall live
    Within the book and volume of my brain,
    William Shakespeare (1564–1616)
