Abstract
A wake-and-go mechanism is provided for a data processing system. When a thread is waiting for an event, rather than performing a series of get-and-compare sequences, the thread updates a wake-and-go array with a target address associated with the event. The wake-and-go mechanism may save the state of the thread in a hardware private array. The hardware private array may comprise a plurality of memory cells embodied within the processor or pervasive logic associated with the bus, for example. Alternatively, the hardware private array may be embodied within logic associated with the wake-and-go storage array.
