‫Welcome to enter your feedback register demonstration on the basis to development board for this demonstration
‫we're using the four digit seven segment display located on the basis to development.
‫We also are using sites which zero to be a reset and or push button zero to give us the next number
‫in our if you back shift register.
‫We're using this when your feedback shift register to generate random numbers where we're displaying
‫the random numbers on the 7 segment display in hexadecimal format.
‫So right now we start out we have our what we call the seed value.
‫In this case is 0 0 1.
‫And since we have 16 bits we have a design in such a way that we have sixty five thousand five hundred
‫thirty five different combinations until we receive one again.
‫So when I pressed button zero and we generate a number 8 000 press again for 0 0 2 1 0 0 8 if I just
‫keep pressing we keep generating numbers.
‫Now if I keep doing this they'll appear to be random it just appears to be Gerring is random hex numbers.
‫But if I go and I reset we go back to 1 and pressed again.
‫Since I've been reset I can press the button.
‫Nothing will happen.
‫A plot of reset.
‫Press the button.
‫Now I guess my a for to reset try again a four two.
‫And so that's where Rickover the term pseudo random because every output is dependent upon the previous
‫input.
‫So it's not truly random.
‫However if in a computer system you have a clock is just clocking real fast.
‫They like this are much faster and you just say stop.
‫And then you say go again.
‫You say stop.
‫These numbers would appear to be random.
‫They're all over the place.
‫And so that is one of the major things you can you lend your feedback shift register for this to generate
‫random numbers such as in your computer whenever you call a function to generate a random number.
‫It most likely has some sort of feedback register used to generate these random numbers as is dependent
‫upon what the seed value is you're placing inside your random number generator to determine what the
‫outcome of the next number.
‫So on and so forth will be known as is when your feedback shift treatise or demonstration running on
‫the base is to board.
