Question 4 State Machines (25 marks) A state machine is required for a simple vending machine. The machine takes one dollar coins only. Each time a coin is added the input signal "coin" is set to 1 for one clock cycle When a total of $4 has been added the output signal "deliver" is set to 1 for one clock cycle and the state machine starts counting coins for the next delivery a) (5 marks) Draw a state diagram for...

Question 4 State Machines (25 marks) a. (5 marks) A 3-bit Gray code counter advances on positive clock edges and generates outputs in the sequence: 000, 001, 011, 010, 110, 111, 101, 100. Draw the assigned state table for a state machine implementing this counter. b. (10 marks) For the Gray code counter in part a, derive (unoptimised) equations for the next state as a function of the current state. c. (10 marks) Consider the following sequence detector. In each...

It has four output patterns: 000, 001, 0111 Tho Te two control signals e counter counts when it is 1 and the counter pauses when it is 0 e counter "increases" (circulating through 000, 0011, 01, 111 and .....pping around) when it is 1 and go is 1. The counter "decreases" (circulating in a reversed pattern, ie., 1 1 11, 01 11, 0011, 0001, and wrapping around) when it is 0 and g0 is l The circuit can be constructed...

random counter,Thanks
Objective: In this lab, we will learn how we can design sequential circuits using behavioral modelling, and implementing the design in FPGA. Problem: Design a random counter with the following counting sequence: Counting Sequence: 04 2 9 168573 Design Description: The counter has one clock (Clock), one reset (Reset), and one move left or right control signal (L/R) as input. The counter also has one 4bit output O and one 2bit output...

3. Finite State Machine. Using a ROM based finite state machine (FSM), design a bi-directional repetitive 3-bit modulo-6 (0,1,2,3,4,5) counter (see Table 3). The design has one input named Dir and three outputs named B2, B1 and BO. The outputs (B2, B1 and BO) are dependent upon being in the present state only. After each clock pulse, when Dir is at logic "O', the outputs (B2, B1, BO) step through the count sequence in following order:- 0,1,2,3,4,5. After each clock...

2. To demonstrate a Mealy state machine, let's design a simple arbiter between two requesting entities. We're going to have two request inputs: reqA and reqB. And two outputs: grantA and grantB. Any combination of requests can be asserted at any time: one of them, both of them, or neither. But at most only one grant can be asserted in any given cycle; if neither request is asserted then neither grant should be asserted. We'll need a state machine to...
