Abstract
One embodiment of the present invention sets forth a technique for synchronization between two or more processors. The technique implements a spinlock acquire function and a spinlock release function. A processor executing the spinlock acquire function advantageously operates in a low power state while waiting for an opportunity to acquire spinlock. The spinlock acquire function configures a memory monitor to wake up the processor when spinlock is released by a different processor. The spinlock release function releases spinlock by clearing a lock variable and may clear a wait variable.
