Hi,

Did TI implemented a locking mechanism which can work between VPSS,VIDEO,C647X processors?

Thanks,

Amit

    816x has  64 instances of h/w spinlock which implements atomic-test-set semantics and can be used multicore locks.IPC package implements  a GateHWSpinlock module using  HWspinlock.Refer ti/ipc/GateMP.h for API. Selecting remote gate type as SYSTEM will create a HWSpinlock instance.
