About the course
Aim
After completing the course the student should be able to
- understand causes and principles of power consumption and energy consumption
- apply techniques to achieve low power consumption on different abstraction levels from systems and algorithms down to circuits
- design systems with low energy dissipation
- estimate and optimise power and energy consumption.
Content
The course deals with important aspects in design of energy-efficient electronic systems such as
- power dissipation in CMOS circuits
- switch activity and switched capacitance
- methods and tools for power estimation
- power estimation on different abstraction levels
- relation between delay and power consumption
- scaling of supply voltage and threshold voltage
- design of CMOS circuits for low supply voltage
- influence of data dependency on power dissipation
- minimising switching and glitches
- algorithm transformations for low power consumption
- clocking or asynchronous techniques
- energy recovery.
