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. (a) In the circuit shown in Figure the zener diode (with zero zener resistance) operates in its reverse breakdown region while the voltage across it is held constant at VZ and t
(a) Figure shows a circuit containing an amplifier block. Find the open-circuit voltage amplification of the circuit. (b) Let the output terminals be connected to a load resista
Q. Explain the different coupling schemes used in amplifiers? When amplifiers are cascaded, it is necessary to use a coupling network between the output of one amplifier and th
Q. Basic working of optical coupler? The optical coupler is suitable for frequencies in the low megahertz range. The photodiode type shown above can handle only small currents;
The subject of electrical measurements is such a large one that entire books have been written on the topic. Only a few basic principles will be introduced here. Practical measurem
