Many multiprocessors distinguish between a cache block that is really shared and one that exists in the clean state in exactly one cache. The addition of a "clean and private" state eliminates the need to generate a bus transaction on a write to such a block. Another enhancement in wide use allows other caches to supply data on a miss to a shared block.
1) Justify the following statement: "The addition of a "clean and private" state eliminates the need to generate a bus transaction on a write to such a block."
2) How to implement the cache protocol to support a "clean and private" state?
Despite the advantages to the synchronous alternator there is a downside and this has to do with keeping the load balanced on such a machine. Why is balancing the load so important to the synchronous alternator?
Dynamic RAM that must be given a refresh cycle 64 times per ms. Each refresh operation requires 150 ns. memory cycle requires 250 ns.
The op-amp circuit measures the changes of temperature in a system. The output voltage is given by v0(t) = -R(t)vi(t). Suppose that the temperature in the system changes cyclically after t = 0, so that R(t) = [1 +0.5 cos(20πt)] u(t) and let the in..
Resistance=0.09ohm/km Inductance=1.4mH/km Capacitance=8.8x10-3 uF/km. Calculate the sending-end power if the receiving-end voltage is 132kV and the receiving-end power is S2=100+j60 MVA. Assume a pi-equivalent circuit.
The heat loss through the exterior walls of a certain poultry processing plant is estimated to cost the owner $3,000 next year. A salesman from Superfiber Insulation, Inc., has told you, the plant engineer, that he can reduce the heat loss by 80%
A sled of mass m is given a kick on a frozen pond. The kick imparts to it an initial speed of 1.60 m/s. The coefficient of kinetic friction between sled and ice is 0.110. Use energy considerations to find the distance the sled moves before it stop..
a) Why is it that if the power system of interest is physically smaller than the wavelength, we can represent it as a lumped-parameter system b) Why a long wavenenth requires a gigantic antennas
A waveform generator is connected to an op-amp which has been setup as a voltage follower. The voltage follower is then loaded with a 50 Ohm resistor. What output impedance setting should the waveform generator use
the doping level of N-type semiconductor is ND = 5x10^19 cm^-3. Determine the room-temperature position of the Fermi level (with respect to the borrom of the conduction band) if the semiconductor is Si (Nc = 2.86x10^19).
Design and implement a Rectangle class. Make your class inherit from the Point class given in the lecture (notice that a rectangle can be described through the upper-left vertex, the height, and the width).
If the U.S. consumes 10 Quads each year by burning gasoline for automobiles, and if this energy usage is spread evenly across 8760 hours in a year, what is the equivalent continuous flow of power in Megawatts (MW)
A system or component is imaginary (critically ) stable if at least one real part of the roots of the characteristic equation is equal to zero. Determine the stability of the following system and design the circuit.
