Abstract:
A hardware wake-and-go mechanism is provided for a data processing system. The wake-and-go mechanism looks ahead in a thread for programming idioms that indicates that the thread is waiting for an event. The wake-and-go mechanism performs a look-ahead polling operation for each of the programming idioms. If each of the look-ahead polling operations fails, then the wake-and-go mechanism updates a wake-and-go array with a target address associated with the event for each recognized programming idiom.
