Consider the router diagram. Consider that the packets shown are uniformly 500kB in size and that they are all stored in the input buffers of ports W, X and Y. These packets marked with the output buffer they are destined for. The switching fabric is a crossbar based design with each crossbar bus operating at 10Mbps.
a) How much time is required to move all the packets from the input port buffers to the output port buffers? Does Head of Line blocking occur?
b) If all the packets in the input port buffer for X are now 1500kB in size but the others remain unchanged. How much time is required to move all the packets to the output port buffers? Does Head of Line blocking occur?
c) How did the variable packet sizes affect the time required to move the packets through the switching fabric?
d) Consider the scenario in part b) but if the router instead "fragmented" each of the larger 1500kB packets into 3 smaller 500kB cells. Assume that these fragmented pieces can be put back together in the output port buffer even if they pass through the fabric out-of-order. How much time is required to move all the packets to the output port buffers?
Explain and discuss the problems presented by electronic discovery in civil actions and how the law has responded.
If a stepper motor has a step-angle of 7.5? , what digital input rate is required to produce a rotation of 10 rev/sec What will be the step-angle for a hybrid stepper motor with eight stator windings and ten rotor teeth
A cable technician tested the signal-to-noise ratio on the curb as 20 dBm. This means, if the noise power is at 1 mW, then the signal power should be 20 dB higher then that. If the noise power is 20 mW
1.Design a finite state machine (FSM) that transitions from 0 to 2 to 4 to 5 to 7 to 0. Write the VHDL code for the FSM. 2.Design a finite state machine that detects two consecutive zeros (0s).
a) Determine the self inductance of coil 1, L11 b) Determine the self inductance of coil 2 L22 c) Determine the mutual inductance between the two coils, L12 or L21
The cylindrical coaxial cable with the cross section shown below, has inner and outer radii of 5mm and 15mm respectively. The dielectric parameters are; er=2, signma=5*10^(-10) S/m and Ur=1.
A sampled-data system such as that presented in problem (i) has a sampling period T = 0.05s and has G(z) = K (z3 + 10.3614z2 + 9.758z + 0.8353) / (z4 - 3.7123z3 + 5.1644z2 - 3.195z + 0.7408) 1. Determine K when the two real poles break away from the ..
The Hamming distance between two bit strings of the same length is the number of positions in which the strings have different bit values. For example, the Hamming distance between 1110 and 0101 is 3.
The IC differential amplifier is to be fabricated in a CMOS technology having the technology specifications of Kn' = 200 uA/V. Kp' = 100 uA/V. Vtn = 1V Vtp = -1V Va = 50V L = 1u. Calculate all the device widths for a constant bias current of 1mA
Interface TTL logic to 120 VAC lamp. In this part of the lab, you will interface lowpower solid state electronics to the "outside world" by switching the 120 VAC lamp on and off using the AND gate from the previous experiment.
