Question

Draw the logic diagram of the circuit according to the given table, where the microoperations occur according to the K1, K2 and K3 signals. Assume that each register stores 3 bits of data.

K1 K2 K3
0 0 0 R2 <- R1
0 0 1 R2 <- R1 (0:2)
0 1 0 R2 <- R1'
0 1 1 R2 <- R2'
1 x x R2 <- R2

I hope someone help me at least share some helpful resource :) The reason why I asked here my teacher doesn't share the lecture resource.

Answer 1

It is a part of answer - decoding from bits entry to 1 channel. It works only with first four combination. And uses only AND and NOT gates.
Using this - you can pass output to perform right microoperators to act.
IDK how do you draw diagrams, so hopefully it could help

Answer 2

If only i could understand (0:2) and '
Can you explain this ?

Answer 3

So i spent 20 minutes of learning syntaxes... Now give me few minutes to draw one component that you need

Answer 4

Thank you Alex

Answer 5

Please folow to posts on my page to look diagrams
