Write a program in Arm Cortex M0+ assembly language to evaluate the performance of the Bubble Sort algorithm concerning array size. To start, create a timer interrupt with the following parameters: the microcontroller frequency is 10Mhz and the timer interrupt period is 4ms. By employing this timer interrupt alongside the SysTick Timer parameters, you can extract the microcontroller's running time (in microseconds).

The provided pseudo code outlines the main function's structure. Your task involves implementing a program that sorts an array using the Bubble Sort algorithm and records execution times according to the element count. The numbers (unsigned) to be sorted are available in "array.txt," and they need to be integrated into your program in the specified sequence. Upon completion, the memory address of the sorted array should be stored in the R0 register, while the memory address of the execution times array should be stored in the R1 register. The program should also save the sorted array and execution times to the memory.

Hint: In the BubbleSort function, make sure to copy only the first 'i' elements of the array into memory. Avoid moving beyond the specified parameter to ensure the function operates within the designated range.

The pseudocode:

void main () { //Initialize System Tick Timer to generate interrupt Init SysTick Timer () ; for (int i=2; i<=ARRAY_SIZE; i++) { //Record the current running time on the microcontroller as the start time. Save_Start_Time () ; //Run Bubble sort algorithm for the first i elements of array. BubbleSort (i) ; //Calculate execution time of BubbleSort function using start time Save_Execution_Time (); } //Stop to System Tick Timer and clear interrupt configuration. Stop SysTick Timer () ; while (1); }

The code should work in Keil Vision IDE v5.
