The Spinlock module provides hardware assistance for synchronizing the processes running on multiple processors in the device:
The Spinlock module implements 256 spinlocks (or hardware semaphores), which provide an efficient way to perform a lock operation of a device resource using a single read-access, avoiding the need of a readmodify- write bus transfer that the programmable cores are not capable of.
For more information, see chapter Spinlock of the Device TRM.
