ABSTRACT:
An embedded system optimally operates with minimal power consumption without sacrificing performance. Power consumption can be reduced by independently and dynamically controlling multiple power partitions, wherein components within a partition can have the same power profile. States of operation can be programmably defined in a table and enforced using hardware. Voltages in the table can be dynamically updated during a runtime of the system using a timing feedback module, which is connected to a critical path in a partition. The timing feedback module can output a vector that indicates the timing margin for that critical path. Using this timing margin, software can increase or decrease the voltage to optimize power consumption of that partition.
