| Aim: In the course we study the design of electronics systems with low power consumption. Methods and tools on the different abstraction levels from system and algorithm levels down to circuits are considered. A small project on power estimation and optimization is included. |
|||
| Prerequisites: (valid for students admitted to programmes within which the course is offered) TSTE86 Digital integrated circuits or a corresponding course in digital circuit design. Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding. |
|||
| Organisation: The course consist of lectures, exercises, laboratory and project work. |
|||
| Course contents: Power dissipation in CMOS circuits. Physical bounds on low power. Switch activity and switched capacitance. Power estimation on different abstraction levels. Methods and tools for power estimation. Strategies for power optimization. Influence of supply voltage scaling and threshold voltage scaling on delay and power consumption. Multiple threshold voltage techniques. Delay balancing to minimize glitches. Synthesis of state machines. Clock distribution. Layout optimization. Design of CMOS and BiCMOS circuits for low supply voltages. Energy recovery in CMOS circuits. Power management: gating the clock, power down, and asynchronism. Algorithms for low power and algorithm transformations on different abstraction levels and data dependency. Architectures for low power. Arithmetics for low power. System partitioning. Programming for low power consumption. |
