AI Technical Summary
In multi-core systems, existing software semaphores or mutexes rely on software interrupts for resource access synchronization, resulting in large response delays, inability to guarantee the atomicity of operations, high synchronization complexity, and difficulty in debugging.
A hardware lock module is introduced, including a hardware lock register module and a hardware lock arbitration response module, to achieve atomic mutual exclusion access at the hardware level and prevent conflicts caused by multiple cores accessing peripheral or memory resources simultaneously.
It implements hardware-level atomic mutual exclusion access, avoids read/write asynchrony and arbitration timing competition, reduces system wait time, improves real-time response of multi-core access, and enhances system operational stability.
