在算术左移位中，位元移动的范围若超过结果资料型别会予以舍弃，而且右方空出的位元位置会设定成零。

In an arithmetic left shift, the bits shifted beyond the range of the result data type are discarded, and the bit positions vacated on the right are set to zero.

利用传输门实现了32位桶式移位寄存器，其具体功能包括算术右移，逻辑左移，逻辑右移和循环右移。

In this paper, we realized Barrel Shifter of 32 bits by using transpost gates, its functions including arithmetic shift right, logic shift left, logic shift right and rotate right.
