Abstract
An apparatus include a first core processor, a second core processor, and a lock register coupled to the first core processor and to the second core processor. The apparatus further includes a shared structure responsive to the first core processor and to the second core processor. The shared structure is responsive to an unlock instruction issued by either the first core processor or the second core processor to send a signal to the lock register to reset a lock indication in the lock register.
Claims23
An apparatus comprising:
- a first core processor;
- a second core processor;
- a lock register coupled to the first core processor and to the second core processor;
- and
- a shared structure responsive to the first core processor and to the second core processor, the shared structure responsive to an unlock instruction issued by either the first core processor or the second core processor to send a signal to the lock register to reset a lock indication in the lock register.
A method comprising:
- receiving an unlock instruction at a memory device, the unlock instruction issued by a first processor;
- and
- sending a signal from the memory device to a data storage device coupled to the first processor to reset a lock state indication stored in the data storage device.
A non-transitory computer readable storage medium comprising instructions that, when executed by a processor, cause the processor to:
- receive, at a shared memory of the processor, an unlock instruction issued by a first core processor;
- and
- send a signal to a data storage device coupled to the first core processor to reset a lock state indication stored in the data storage device.
An apparatus comprising:
- means for storing a lock state indication;
- means for sending a signal to the means for storing responsive to receiving an unlock instruction, wherein the lock state indication stored in the means for storing is reset based on the signal;
- and
- means for releasing a lock;
- and
- means for performing other processing functions upon release of the lock and prior to the lock indication being reset, the unlock instruction issued to the means for sending after the lock is released.
