Assertion (computing) - Use in Computer Circuits

Use in Computer Circuits

In computer hardware design, the term assert usually means to make an electrical signal active, as opposed to quiescent. For example, if a narrative says "IRQ is asserted" and IRQ is defined to be low true, the narrative is saying that the IRQ signal was brought to the logic 0 state (usually near zero volts), implying that IRQ's quiescent state is logic 1 (a voltage substantially above the logic 0 level). In other words, a signal is said to be asserted if its state is made the opposite of what it would be when not in use.

    The Buddha, the Godhead, resides quite as comfortably in the circuits of a digital computer or the gears of a cycle transmission as he does at the top of a mountain or in the petals of a flower.
