Temporal Multithreading - Comparison To Simultaneous Multithreading

Comparison To Simultaneous Multithreading

In any of its forms, temporal multithreading is similar in many ways to simultaneous multithreading. As in the simultaneous process, the hardware must store a complete set of states per concurrent thread implemented. The hardware must also preserve the illusion that a given thread has the processor resources to itself. Fairness algorithms must be included in both types of multithreading situations to prevent one thread from dominating processor time and/or resources.

Temporal multithreading has an advantage over simultaneous multithreading in that it causes lower processor heat output; however, it allows only one thread to be executed at a time.

Famous quotes containing the words comparison to, comparison and/or simultaneous:

    It is very important not to become hard. The artist must always have one skin too few in comparison to other people, so you feel the slightest wind.
    Shusha Guppy (b. 1938)

    We teach boys to be such men as we are. We do not teach them to aspire to be all they can. We do not give them a training as if we believed in their noble nature. We scarce educate their bodies. We do not train the eye and the hand. We exercise their understandings to the apprehension and comparison of some facts, to a skill in numbers, in words; we aim to make accountants, attorneys, engineers; but not to make able, earnest, great- hearted men.
    Ralph Waldo Emerson (1803–1882)

    Ours is a brand—new world of allatonceness. “Time” has ceased, “space” has vanished. We now live in a global village ... a simultaneous happening.
    Marshall McLuhan (1911–1980)
