    C#, since .NET Framework 4.5, [22] via the keywords async and await [23] Kotlin, however kotlin.native.concurrent.Future is only usually used when writing Kotlin that is intended to run natively [35] Nim; Oxygene; Oz version 3 [36] Python concurrent.futures, since 3.2, [37] as proposed by the PEP 3148, and Python 3.5 added async and await [38]

  3. Group delay and phase delay - Wikipedia

    en.wikipedia.org/wiki/Group_delay_and_phase_delay

    The group delay and phase delay properties of a linear time-invariant (LTI) system are functions of frequency, giving the time from when a frequency component of a time varying physical quantity—for example a voltage signal—appears at the LTI system input, to the time when a copy of that same frequency component—perhaps of a different physical phenomenon—appears at the LTI system output.

  4. Exponential backoff - Wikipedia

    en.wikipedia.org/wiki/Exponential_backoff

    After the second collision, the senders will wait anywhere from 0 to 3 slot times . After the third collision, the senders will wait anywhere from 0 to 7 slot times (inclusive), and so forth. As the number of retransmission attempts increases, the number of possibilities for delay increases exponentially. This decreases the probability of a ...

  5. Object lifetime - Wikipedia

    en.wikipedia.org/wiki/Object_lifetime

    Aspects of object lifetime vary between programming languages and within implementations of a language. The core concepts are relatively common, but terminology varies. For example, the concepts of create and destroy are sometimes termed construct and destruct and the language elements are termed constructor (ctor) and destructor (dtor).

  6. Delay calculation - Wikipedia

    en.wikipedia.org/wiki/Delay_calculation

    Elmore delay [5] is a simple approximation, often used where speed of calculation is important but the delay through the wire itself cannot be ignored. It uses the R and C values of the wire segments in a simple calculation. The delay of each wire segment is the R of that segment times the downstream C. Then all delays are summed from the root.

  7. Broadcast delay - Wikipedia

    en.wikipedia.org/wiki/Broadcast_delay

    From the Rahal brothers' stations, the broadcast profanity delay went into common usage throughout the US. [citation needed] John Nebel, who began a pioneering radio talk show in New York City in 1954, was one of the early users of a tape delay system that was invented by his engineer, Russell Tinklepaugh. [3]

  8. Quasi-delay-insensitive circuit - Wikipedia

    en.wikipedia.org/wiki/Quasi-delay-insensitive...

    A quasi-delay-insensitive circuit (QDI circuit) is an asynchronous circuit design methodology employed in digital logic design.Developed in response to the performance challenges of building sub-micron, multi-core architectures with conventional synchronous designs, QDI circuits exhibit lower power consumption, extremely fine-grain pipelining, high circuit robustness against process–voltage ...

  9. Predication (computer architecture) - Wikipedia

    en.wikipedia.org/wiki/Predication_(computer...

    Other detriments are the following: [3] Predication complicates the hardware by adding levels of logic to critical paths and potentially degrades clock speed. A predicated block includes cycles for all operations, so shorter paths may take longer and be penalized. Predication is not usually speculated and causes a longer dependency chain.
