Abstract
An integrated circuit comprises first and second power domains, and a message handling unit to control passing of messages sent from a sender device in the first power domain to a receiver device in the second power domain. The message handling unit writes messages sent from the sender device to a message storage area, provided in the second power domain. The message handling unit is responsive to a message send request from the sender device requesting sending of at least one message to the receiver device when at least one device in the second power domain is in a quiescent state, to transmit a wakeup request to a second domain power controller to request that said at least one device in the second power domain transitions from the quiescent state to an awake state.
