However, this new code now assumes that the starting address is 16-byte aligned, and also that it has enough padding on the end that the next data element in memory is also 16-byte aligned.

然而，这段新代码假定起始地址是按照16字节对齐的，并且末尾也有足够的填充位，因此内存中下一个数据元素也是16字节对齐的。

The part of a two-part memory address that remains constant and provides a reference point from which the location of a byte of data can be calculated.

保持恒定的两部分内存地址的一部分并提供一个基准点，从这里可以计算一个字节数据的位置。

youdao

Every time a memory location is addressed for program instructions or data, a virtual address is translated into a physical or real memory address.

每次为程序指令或数据处理内存位置时，都需要将虚拟地址转换成物理(或实际)内存地址。
