In computer architecture, a delay slot is an instruction slot being executed without the effects of a preceding instruction. [1] The most common form is a single arbitrary instruction located immediately after a branch instruction on a RISC or DSP architecture; this instruction will execute even if the preceding branch is taken.
Logical effort provides a simple delay calculation that accounts for gate sizing and is analytically tractable. Similarly, there are many ways to calculate the delay of a wire. The delay of a wire will normally be different for each destination. In order to increase accuracy (and decrease speed), the most common methods are: Lumped C. The ...
In a binary exponential backoff algorithm (i.e. one where b = 2), after c collisions, each retransmission is delayed by a random number of slot times between 0 and 2 c − 1. After the first collision, each sender will wait 0 or 1 slot times. After the second collision, the senders will wait anywhere from 0 to 3 slot times . After the third ...
In Kendall's notation, the M/M/1/K queuing model, where K is the size of the buffer, may be used to analyze the queuing delay in a specific system. Kendall's notation should be used to calculate the queuing delay when packets are dropped from the queue. The M/M/1/K queuing model is the most basic and important queuing model for network analysis ...
The settling time for a second order, underdamped system responding to a step response can be approximated if the damping ratio by = () A general form is T s = − ln ( tolerance fraction × 1 − ζ 2 ) damping ratio × natural freq {\displaystyle T_{s}=-{\frac {\ln({\text{tolerance fraction}}\times {\sqrt {1-\zeta ^{2}}})}{{\text ...
In mathematical queueing theory, Little's law (also result, theorem, lemma, or formula [1] [2]) is a theorem by John Little which states that the long-term average number L of customers in a stationary system is equal to the long-term average effective arrival rate λ multiplied by the average time W that a customer spends in the system.
The delay locked loop is a variable delay line whose delay is locked to the duration of the period of a reference clock. Depending on the signal processing element in the loop (a flat amplifier or an integrator), the DLL loop can be of 0th order type 0 or of 1st order type 1.
Elmore delay [1] is a simple approximation to the delay through an RC network in an electronic system. It is often used in applications such as logic synthesis, delay calculation, static timing analysis, placement and routing, since it is simple to compute (especially in tree structured networks, which are the vast majority of signal nets within ICs) and is reasonably accurate.
