What are the three basic elements of ASM chart?

Following are the three basic components of ASM charts.

  • State box.
  • Decision box.
  • Conditional output box.

What does the state box in an ASM chart represent?

The ASM chart determines the sequence of events, timing relationship between the states of sequential controller and the events that happen while going from one state to another. A state in the control sequence is described by State box.

What are the three basic elements in an ASM chart Mcq?

There are three basic elements of ASM charts : State box. Decision box. Condition box.

How does ASM chart differ from software flowchart?

ASM is an algorithm consists of a few steps, which is used to simplify a sequential digital system. An ASM chart is resembles a conventional flow chart but the difference is, a conventional flow chart does not have timing relationships but the ASM takes timing relationship into account.

When implementing a circuit from a ASM chart we do these steps in order?

Step 1 : Decide the type and number of flip-flops to be used. Step 2 : Draw the K maps for the inputs of all flip-flops as well as circuit output using the transition table. Step 3 : Obtain the simplified Boolean expression for it inputs and circuit outputs. Step 4 : Draw the logic diagram.

What is an ASM block explain how the ASM chart differs from a conventional flow chart?

What is an ASM block?

ASM block. • The state box represents the state in the FSM, and the output in the state box describes the desired output values when the FMS enters this state (i.e. the Moore outputs). • The decision box tests an input condition to determine the exit path og the current ASM block.

How many levels are there in multiplexer design method of ASM chart?

The multiplexer method of design has three levels of components, as shown in Figure below. The multiplexer outputs are applied to the flip flops forming the register at second level. The second level register is used for holding the present binary state.

What is the smallest number of flip flops needed to implement a state machine with five states?

3 flip flops
It is interesting to note that the implementation of our 5-state FSM requires only 3 flip flops, in contrast to the 4-bit shift register implementation shown in Section 9.1.

What is the third level of designing ASM charts using multiplexer?

ASM using Multiplexer controller Method:- 1 2. The multiplexers decide the next state of the register as outputs of MUX has been connected to flip-flop inputs. 3. Third level is the decoder which provides separate output for each control state.
