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.

在算术右移位运算中，将丢弃移出最右侧数位位置的数位，并将最左侧的数位传播到左端空出的数位位置。

In an arithmetic right shift, the bits shifted beyond the rightmost bit position are discarded, and the leftmost bit is propagated into the bit positions vacated at the left.
