In the context of "dark silicon," what architectural challenge does this term describe for modern chip design?
Correct! Well done.
Incorrect.
The correct answer is A) As transistor density increases (per Moore's Law) but power density limits how much of a chip can be active at once, an increasing fraction of its transistors must stay powered off ("dark") at any time to stay within thermal limits
Correct Answer
As transistor density increases (per Moore's Law) but power density limits how much of a chip can be active at once, an increasing fraction of its transistors must stay powered off ("dark") at any time to stay within thermal limits
Dark silicon reflects the gap between the number of transistors that can be fabricated on a chip and the number that can be simultaneously powered without exceeding thermal design limits, driving architectural trends like specialized accelerators and heterogeneous cores that activate only when needed.
