Question:
(a) Explain the following metrics: (i) Throughput (ii) Latency (iii) IPC
(b) Of the three factors in the equation (EXCPU = Number of instructions × CPI × cycle time), which is most influenced by:
(i) The technology (ii) The compiler (iii) The computer architect
(c) State Moore'law.
(d) Explain why technically the clock frequency attained its maximum to 3 GHz in around year 2003.
(e) Illustrate Amdahl's law in terms of speedup vs. sequential portion of program by showing the speedup for N = 8 processors when the sequential portion of the program grows from 1% to 25%
(f) With sequential execution occurring 15% of the time:
(i) What is the maximum speedup with an infinite number of processors?
(ii) How many processors are required to be within 20% of the maximum speedup?
(iii) How many processors are required to be within 2% of the maximum speedup?
Q. Determine the current I through the 10- resistor of the circuit of Figure by employing the node-voltage method. Check by mesh analysis.
Semiconductor in Equilibrium Equilibrium in semiconductors implies the following: (i) Steady state: ∂Z / ∂t = 0 In which Z is any physical quantity like charge, volt
Q. The speed of an 8-bit A/D converter is limited by the counter, which has a maximum speed of 4 × 10 7 counts per second. Estimate the maximum number of A/D conversions per secon
To have the same value of P e , show that E b /N 0 in a coherent-ASK system has to be twice that in a coherent PSK system.
8 bit data to Register This form of the instruction is used to copy 8 bit data directly to the register location specified in the instruction. The instruction format i
The mechanical power produced at the armature of a motor is: P = T a . (power is in watts if torque is N.m and in rad/sec). Some of this will be lost due to friction and
Power Diode A power diode is a two terminal, anode a and cathode K and two layer P and N junction devices. A PN junction normally formed by allowing diffusion and epita
A three-phase transposed line is composed of one ACSR conductor per phase with flat horizontal spacing of 11 meters as shown in Figure (a). The conductors have a diameter of 3.625
Why is the signal first attenuated and then amplified?
There are three types of buses. Address bus: This is used to carry the Address to the memory to get either Instruction or Data. Data bus : This is used to take the Data from
