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?
Comparison of Analog-Modulation Systems The comparison of analog modulation systems (conventional AM, DSB SC, SSB SC, VSB, FM, and PM) can be based on three practical criteria:
Q. Considering the circuit shown in Figure, sketch v(t) and the energy stored in the capacitor as a function of time.
Need for Modulation Recognition There are so many communication signals all available with different types of modulation and different frequencies. It is necessary to identify
Q. Figure can also be considered as a simple model of a magnetically operated relay that is commonly used for the automatic control and protection of electric equipment. Consider t
