| description | The embodiment of the invention discloses a critical area locking method, a device, a terminal and a storage medium. The method comprises the following steps: if receiving an access instruction of anythread in a critical region to a common resource, obtaining a current value of a lock state parameter of the critical region; comparing whether the current value of the lock state parameter is equalto the initial value of the lock state parameter by an atomic operation mode; adjusting the value of the lock state parameter according to the comparison result; responding to the access instruction according to the comparison result; and controlling the locking state of the critical region. By adopting the technical proposal of the invention, the system performance can be improved while maintaining the consistency of the common resource data of the critical region.
