Question

Suppose we have developed new versions of a processor with the following characteristics: Version Voltage Clock rate 1 1.5 V 2.4 GHz 2 1.2 V 3 GHz a) How much has the capacitive load varied between versions if the dynamic power has been reduced by 15%? b) Assuming that the capacitive load of version 2 is 70% the capacitive load of version 1, find the new voltage value for version 2 if the dynamic power of version 2 is reduced by 35% from version 1. c) Assuming you run a certain benchmark program on version 1 and 30% of the execution time is consumed on ALU instructions, how much improvement can be achieved in the execution time if the ALU unit was enhanced by a factor of 2? d) Assuming you run a certain benchmark program on version 1 and 30% of the execution time is consumed on ALU instructions, Can the ALU unit by enhanced for an overall 1.5x improvement? Why?

          Suppose we have developed new versions of a processor with the following characteristics:

Version	Voltage	Clock rate
1	1.5 V	2.4 GHz
2	1.2 V	3 GHz
a) How much has the capacitive load varied between versions if the dynamic power has been
reduced by 15%? 
b) Assuming that the capacitive load of version 2 is 70% the capacitive load of version 1, find the
new voltage value for version 2 if the dynamic power of version 2 is reduced by 35% from
version 1.
c) Assuming you run a certain benchmark program on version 1 and 30% of the execution time
is consumed on ALU instructions, how much improvement can be achieved in the execution
time if the ALU unit was enhanced by a factor of 2?
d) Assuming you run a certain benchmark program on version 1 and 30% of the execution time
is consumed on ALU instructions, Can the ALU unit by enhanced for an overall 1.5x
improvement? Why?
