UCR CS269:
Hardware/Software Engineering of Embedded Systems
Architecture Optimizations
•An additional source of power efficiency comes from extending power management to include control on the CPU’s voltage and performance.
•Dynamic voltage/freq
has high potential, but required a
unified hw/sw approach.
•Multi-media applications are ideally suited for dynamic voltage/freq scaling since they often have regular activity patterns that can be pre-characterized.
