ABSTRACT:
Methods and arrangements to configure power management systems for integrated circuits are provided herein. A group of IC components that are functionally distinct or have mutually exclusive and/or quasi-mutually exclusive, (ME/QME) operating patterns (i.e. alternate or partially overlapping duty cycles) can be powered with a single power cell. An integrated circuit design tool can identified components in an integrated circuit design that have the ME/QME operating patterns. These cells can be collocated in close proximity to each other and power management system components can be placed in this area such that a multiple signal processing cells can share a single power line and a single power cell. Such a configuration can greatly reduce the size of a power management system for an integrated circuit.
