But on arm platforms, 112* 113* Data Memory Barrier acts as a memory barrier. It ensures that all explicit 114* memory accesses that appear in program order before the DMB instruction are 115* observed before any explicit memory accesses that appear in program order 116* after the DMB instruction. It does not affect the ordering of any other 117* instructions executing on the processor 118* 119* Data Synchronization Barrier acts as a special kind of memory barrier. No 120* instruction in program order after this instruction executes until this instruction 121* completes. This instruction completes when: 122* 1. All explicit memory accesses before this instruction complete. 123* 2. All Cache, Branch predictor and TLB maintenance operations before 124* this instruction complete. 125* 126* @param[in] void 127* 128* @returns void 129* 130* @remarks none 131* 132******************************************************************************* 133*/ 134 135#endif /* IH264E_PLATFORM_MACROS_H_ */ 136
