[Full Paper (pdf) , 460 kB]
This diploma thesis shows that an operating system aware of detailed information
about the processes it serves is able to save energy by means of performance
monitoring counters and dynamic frequency scaling. A model for
controlling dynamic frequency scaling based on performance monitoring information
called Process Cruise Control is presented. For its implementation the
Cyclone IQ 80310 development-board was selected as the target platform. Together
with an XScale architecture CPU, the Intel 80200 processor performance
monitoring counters, as well as frequency scaling, are available.
