Energy Management Techniques for SoC

(True/False)

Software running on a chip does not contribute any impact of energy consumption of the chip.

• True

• False

(True/False)

Power dissipated during a short circuit is considered as dynamic power.

• True

• False

(True or False)

Reducing the supply voltage always leads to a decrease in dynamic power consumption.

• True

• False

(True/False)

Larger load capacitance increases the speed of operation.

• True

• False

Power that the gate dissipates during the absence of switching activity is ..

• AC power

• Static power

• DC power

• Dynamic power

Power dissipated due to switching of gates is ..

• AC power

• Static power

• DC power

• Dynamic power

By ignoring switching activity, which of this relationship of Energy (E) and Power (P) is FALSE:

These are possible techniques to reduce power dissipation of a circuit EXCEPT:

• Reduce switching activity

• Reduce threshold voltage

• Reduce voltage supply

• Reduce memory size

The impact of wide datapath to power dissipation of a circuit:

• P(dyn) increased, P(leak) increased

• P(dyn) decreased, P(leak) increased

• P(dyn) increased, P(leak) decreased

• P(dyn) decreased, P(leak) decreased

Leakage power can be reduced using the following techniques EXCEPT:

• Shifting circuit to low leakage

• Cooling mode for high temperature parts

• Increase the number of transistors
