Hi!
The question: Define the ideal case, the dynamic dissipation is reduced when using dual-core CPU when running the application has not changed? (The application be partitioned into two parts, namely the frequency of each core half enough to run. Suppose further that the core voltage reduced proportionally to the frequency) alternatives:
a: half
b: 1 / 8
c: 30%.
d: 1 / 4.

i found some formulas about this but i cant see how to change them when theres 2 or more cores
