base pointer

基本解释

To access the third field, you would specify register X as the base pointer and 12 as the offset.
要访问第三个域，我们需要指定寄存器 X 作为指针，12 作为偏移量。
So, using base-pointer addressing, you would specify register X as the base pointer and 8 as the offset.
因此，使用基指针寻址模式，我们可以指定寄存器 X 作为基指针，8 作为偏移量。
You then use register 127 as your loop counter and register 126 as your base pointer, and perform convert_to_upper on each value until you get to the end of the buffer.
然后再将寄存器 127 用作循环计数器，将寄存器 126 用作基指针，并在每个值上执行 convert_to_upper，直到到达缓冲区的底部为止。
