Post subject: | MSYNC指令 |
MSYNC指令: 用途...當您需要load store memory都是按照順序時,要用這個指令。 它也有intrinsic function可以用,請查programming guide。 在N801-S的datasheet上有描述。 2. Memory Address Space Attributes N801-S processor core is targeted on small systems which do not require memory management. Therefore, N801-S processor core provides neither virtual-to-physical address translations nor memory address space attribute definitions. The memory address space attributes are decided based on the SoC-level implementations. To enforce certain ordering between the loads and store memory operations, MSYNC instructions must be inserted in the program sequence. |
