| * @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 |
