The data word processor 606 handles the in-flow and out-flow of byte-oriented input/output data and interleaved signals at a rate of, for example, 500 kilobytes per second. Instruction processing rates of four to eight per microsecond are required for such a data flow.

1966 March, Thomas Pynchon, chapter 6, in The Crying of Lot 49, New York, N.Y.: Bantam Books, published November 1976, →ISBN, page 136:Hxh son all day any week and any hour any minute any second, any millisecond, any microsecond, any nanosecond any picosecond any femtosecond, any attosecond, any zeptosecond, any yoctosecond, any rontosecond, any quectosecond
2025 May 23, King Chimera (chimera_4212), X:O₂^(•−) and OH^• are highly unstable (half-life at the level of microseconds and nanoseconds, respectively) and cannot cross membrane, while H₂O₂, though not a free radical but a ROS, is relatively stable (half-life around 1 ms) (Møller et al. 2007) and can cross membranes through aquaporins.
2015, Rup Kumar Kar, “ROS Signaling: Relevance with Site of Production and Metabolism of ROS”, in Dharmendra K. Gupta, José M. Palma, Francisco J. Corpas, editors, Reactive Oxygen Species and Oxidative Damage in Plants Under Stress, Springer, →ISBN, page 117:The hemifused intermediate state dominates on the microsecond time scale, with a decay t_(1/2) of 6.3 μs. […] On the submillisecond time scale, long-lived hemifusion intermediates dominate; this population decays over a time scale of several microseconds (t_(1/2) = 6.3 μs) to yield fully fused vesicles.
