2.8 Spinlock Module Overview
The Spinlock module provides hardware assistance for synchronizing the processes running on multiple
processors in the device:
•
•
ARM Cortex-A8 processor
Media Controller
The Spinlock module implements 128 spinlocks (or hardware semaphores) that provide an efficient way to
perform a lock operation of a device resource using a single read-access, avoiding the need for a read-
modify-write bus transfer of which the programmable cores are not capable.
