100 bits left-right rotator 构建一个 100-bit left/right rotator,,并具有同步加载(synchronous load)和左/右启用功能(left/right enable)。旋转器从寄存器的另一端移入移出的位( shifts-in the shifted-out bit),而移位器则丢弃移出的位并移入零。如果启用,旋转器会旋转位,而不会修改/丢弃它们。 load:使...
Build a 100-bit left/right rotator, with synchronous load and left/right enable. A rotator shifts-in the shifted-out bit from the other end of the register, unlike a shifter that discards the shifted-out bit and shifts in a zero. If enabled, a rotator rotates the bits around and does ...
Problem 110:3-bit LFSR使用Verilog 实现上图中的时序电路,假设你要在 DE1-SoC 教学板上实现这个电路,将输入端口 r 连接到板子上的拨动开关,clock 端口接到按键 KEY[0],端口 L 接到按键 KEY[1]。输出端口 Q 连接到板子上的红色 LED。本题原理与上一题相同,但加入了一个板子和其外部接口 ...
Shift Register using verilog We will now consider a shift register. Our shift register has an s_in input entering on its left hand side. At each clock cycle, the content of the register shifts to the right and s_in enters into the leftmost bit or the MSB bit. The whole design also ...
Now changeOverflowActiontoWrap. In this case, most significant bits shift off the "top" ofauntil the value is zero. a = fi(3,1,16,0,'OverflowAction','Wrap');fork=0:16 b=bitshift(a,k); disp([num2str(k,'%02d'),'. ',bin(b)]);end ...

Build a four-bit shift register that also acts as a down counter. Data is shifted in most-significant-bit first when shift_ena is 1. The number currently in the shift register is decremented when count_ena is 1. Since the full system doesn't ever use shift_ena and count_ena together,...
