That means that words will be 4-byte aligned, halfwords will be 2-byte aligned, and bytes don't have to be aligned at all.
这意味着字将是4字节对齐的，半字将是2字节对齐的，而字节则不需要对齐。
The memory allocator must give you a 16-byte aligned block of space, because, in general, memory allocation must provide suitable alignment so that the memory can be used for any purpose.
