* @brief Data Memory Barrier, Data Synchronization Barrier
|
|
*
|
|
*
|
|
* @par Description: These functions do nothing on x86 side. But on arm platforms,
|
|
*
|
|
* Data Memory Barrier acts as a memory barrier. It ensures that all explicit
|
|
* memory accesses that appear in program order before the DMB instruction are
|
|
* observed before any explicit memory accesses that appear in program order
|
|
* after the DMB instruction. It does not affect the ordering of any other
|
|
* instructions executing on the processor
|
|
*
|
|
* Data Synchronization Barrier acts as a special kind of memory barrier. No
|
|
* instruction in program order after this instruction executes until this instruction
|
|
* completes. This instruction completes when:
|
|
* 1. All explicit memory accesses before this instruction complete.
|
|
* 2. All Cache, Branch predictor and TLB maintenance operations before
|
|
* this instruction complete.
|
|
*
|
|
* @param[in] void
|
|
*
|
|
* @returns void

*

* @remarks none
