1. implement 2 bit counter using a fsm, draw the circuit using D flipy flops
I don't understand fsm, like use gray code 00-->01-->11-->10-->00
but for fsm, how is working?
2.simple logic questions that involved using gates to implement boolean
equations, the only one I remember is B = 2*A
How to do? | s*****y

1. note that the bit is coming 1 by 1, so you need to design the state
machine to consider the position of current bit
2. just left shift A
flops

发帖数: 5415 | 3 2正解。不过2*A不算布尔代数吧？也就是有个power of 2在这，要不然就搞大了。
至于1...2-bit counter一共就4个状态吧？input为1时换，为0时stay...这个current
bit的概念是？
