摘要： A wake-and-go mechanism is provided for a data processing system. The wake-and-go mechanism recognizes a programming idiom, specialized instruction, operating system call, or application programming interface call that indicates that a thread is waiting for an event. The wake-and-go mechanism updates a wake-and-go array with a target address, expected data value, and comparison type associated with the event. The thread then goes to sleep until the event occurs. The wake-and-go array may be a content addressable memory (CAM). When a transaction appears on the symmetric multiprocessing (SMP) fabric that modifies the value at a target address in the CAM, logic associated with the CAM performs a comparison based on the data value being written, expected data value, and comparison type.

摘要： A programming language may include hint instructions that may notify a programming idiom accelerator that a programming idiom is coming. An idiom begin hint exposes the programming idiom to the programming idiom accelerator. Thus, the programming idiom accelerator need not perform pattern matching or other forms of analysis to recognize a sequence of instructions. Rather, the programmer may insert idiom hint instructions, such as an idiom begin hint, to expose the idiom to the programming idiom accelerator. Similarly, an idiom end hint may mark the end of the programming idiom.

摘要： A hardware private array is a thread state storage that is embedded within the processor or within logic associated with a bus or wake-and-go logic. The hardware private array and/or wake-and-go array may have a limited storage area. Therefore, each thread may have an associated priority. If there is insufficient space in the hardware private array, then the wake-and-go mechanism may compare the priority of the thread to the priorities of the threads already stored in the hardware private array and wake-and-go array. If the thread has a higher priority than at least one thread already stored in the hardware private array and wake-and-go array, then the wake-and-go mechanism may remove a lowest priority thread, meaning the thread is removed from hardware private array and wake-and-go array and converted to a flee model.

摘要： A wake-and-go mechanism is provided with a central repository wake-and-go array for a multiple processor data processing system. The wake-and-go mechanism recognizes a programming idiom that indicates that a thread running on a processor within the multiple processor data processing system is waiting for an event. The wake-and-go mechanism updates a central repository wake-and-go array with a target address associated with the event. Each entry in the central repository wake-and-go array may include a thread identification (ID), a central processing unit (CPU) ID, the target address, the expected data, a comparison type, a lock bit, a priority, and a thread state pointer, which is the address at which the thread state information is stored.

摘要： A wake-and-go mechanism is provided for a microprocessor. The wake-and-go mechanism looks ahead in the instruction stream of a thread for programming idioms that indicates that the thread is waiting for an event. If a look-ahead polling operation succeeds, the look-ahead wake-and-go engine may record an instruction address for the corresponding idiom so that the wake-and-go mechanism may have the thread perform speculative execution at a time when the thread is waiting for an event. During execution, when the wake-and-go mechanism recognizes a programming idiom, the wake-and-go mechanism may store the thread state in the thread state storage. Instead of putting thread to sleep, the wake-and-go mechanism may perform speculative execution.

摘要： 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.

摘要： A wake-and-go mechanism is provided for a data processing system. The wake-and-go mechanism recognizes a programming idiom that indicates that a thread is spinning on a lock. The wake-and-go mechanism updates a wake-and-go array with a target address associated with the lock and sets a lock bit in the wake-and-go array. The thread then goes to sleep until the lock frees. The wake-and-go array may be a content addressable memory (CAM). When a transaction appears on the symmetric multiprocessing (SMP) fabric that modifies the value at a target address in the CAM, the CAM returns a list of storage addresses at which the target address is stored. The wake-and-go mechanism associates these storage addresses with the threads waiting for an even at the target addresses, and may wake the thread that is spinning on the lock.

摘要： A wake-and-go mechanism is provided for a data processing system. The wake-and-go mechanism is configured to issue a look-ahead load command on a system bus to read a data value from a target address and perform a comparison operation to determine whether the data value at the target address indicates that an event for which a thread is waiting has occurred. In response to the comparison resulting in a determination that the event has not occurred, the wake-and-go engine populates a wake-and-go storage array with the target address and snooping the target address on the system bus without data exclusivity. In response to the comparison resulting in a determination that the event has occurred, the wake-and-go engine issues a load command on the system bus to read the data value from the target address with data exclusivity.
