Lab Assignment # $2$

Using a Linear Feedback Shift Register $($LFSR$)$ as shown below, write a code that generates a sequence of random numbers from $1$ to $65535.$ Save the numbers in an array and check that the generated sequence contains no repetitions.

For the random number generator use the following approach, and write a function named generateRand$()$ that generates the whole sequence and saves it in an array. The function should have the mask used as a random number generator as an argument, and return a pointer to the generated array.

You need to use the function count the number of ones in a register written in a previous lab. Once the array is generated, write another function that checks that the generated array does not contain any repetitions.

Submit your code in a well$-$structured file $($hw$2\_$your$\_$id$.$asm$),$ with comments and good separations between the different functions.

The code should contain the following functions:

The main function, which mainly consists of calling other functions

array$\_$pointer generateRand$($mask$)$:

with mask as input, and pointer to the generated array as output

this function may need to call the function

int count$\_$number$\_$of$\_$ones$($integer$),$ this function counts the number of ones in the input integer passed as a register, and returns the number of ones in another register.

This function is mainly used to compute the output of the XOR gates in the LFSR$.$

int check$\_$repetitions$($array pointer$)$: this function checks that the generated array does not contain any repetitions.

It has a pointer, to the generated array, as input

returns $0$ if the array has no repetitions, and $1$ if there are any repetitions.

To finally check that your code is working properly, display the array as integer numbers separated by a new line, copy paste the output on an Excel sheet and sort the numbers to visually check that there are no repetitions.
