• The start address of dst must be aligned to the number of bytes occupied by the corresponding data type.
• The start address of src must be 32-byte aligned.
• If multiple asc_copy_ub2gm instructions need to be executed and the destination addresses of the asc_copy_ub2gm instructions overlap, a synchronization instruction must be inserted to ensure serialization of multiple asc_copy_ub2gm instructions and prevent abnormal data.
• Synchronous computation includes synchronization wait.
