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.
