Exercise 3 A simple computer bus can only do bus reading. When the input Read_Bus is low the bus is in the state Idle, but when it is high the bus reads three words A, B, C in this order, each one takes one clock cycle to be performed. After reading C, if Read_Bus is still high, the bus performs the reading again in the same order without coming back to the state Idle. 1) 2) 3) 4) Draw the state diagram of this machine Derive the state table Derive the transition table From the Karnaugh maps find the simplified logic equations corresponding to the inputs of the Flip-Flops Draw the logic diagram of the system 5)
