Abstract: A method and apparatus for lock allocation control. When a processor core acquires a lock, other processor cores do not need to constantly poll memory to check whether the required lock is released. Instead, other processor cores will be in sleep state and the next processor core needed will be selectively woken up based on predetermined rule, such that an out-of-order lock contention procedure is turned into an in-order lock allocation procedure. By selectively waking up a processor core that is in sleep state, the method and apparatus can avoid occupying a large amount of bus bandwidth, can avoid cache misses, and can save power consumption of chip.
