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?
There is often a need to produce more than one voltage from a single supply using a voltage divider. For example, the memory components of many personal computers require voltages
Two pure sine waves have similar amplitude "A" and frequency "f." They are out of phase through 180 degrees. If these two signals are added, the resulting waveform will be:
A very widely used alternative form of synchronous motor is the ' indu c tion motor'. This has the advantage that it does not require an auxiliary motor to run the rotor up t

Q. A charge q(t) = 50 + 1.0t C flows into an electric component. Find the current flow.
Q. A 60-Hz, 440-V, three-phase system feeds two balanced wye-connected loads in parallel. One load has a per-phase impedance of 8 + j3 and the other 4 - j1 . Compute the real po

Execution Unit receives program instruction codes and data from BIU, implements these instructions and store the result in general registers.
The sinusoidal voltage source in the circuit shown in Fig. is developing an rms voltage of 2000 V. The 4 ? load in the circuit is absorbing four times as much average power as the
