Question 1

what is DataPath

Answer 1

it is the path (that the data take ) between memory ALU and register

Question 2

who generate Control Signal?

Answer 2

control unit or cu

Question 3

what does the control signal do

Answer 3

it set up the datapath for each step
(AKA set the dataflow direction on communication buses and select ALU and memory function )

Question 4

what is Sequential system?
ما هو النظام التتابعي ؟

Answer 4

it is a system contain a state store in memory element
and it behavior depends on both the input and the state (or the value stored in the internal memory element)

Question 5

can we describe a sequential system with the truth table ?

Answer 5

no but it can be described as finite state machine

Question 6

how can we determines the next state of
the system in the FSM

Answer 6

by looking to the combination of the current state and the input

Question 7

If the output function can depend on both the current state and
the current input, the machine is called ?
1- Mealy Machine
2- Moore Machine

Answer 7

1-Mealy Machine

Question 8

If the output function is only depend on the current state the machine is called ?
1- Mealy Machine
2- Moore Machine

Answer 8

2-Moore Machine

Question 9

it is store the type of the instruction (R-type or J-type or I-type) ?
1- RS
2- RT
3- RD
4- Opcode
5- Funct
6- shift

Answer 9

5- Funct

Question 10

it is store the what is the instruction ?
1- RS
2- RT
3- RD
4- Opcode
5- Funct
6- shift

Answer 10

5- Funct
