One of the common operations in signal processing is to compare one set of data (that represents a curve or a function) with other sets of data that represent other curves and find the closest match. The closest match can be called when the error resulting from the comparison of each two curves is minimized. The error can be calculated based on the following formula:SAD = ∑n-1(ai - bi) i=0SAD is the sum of absolute differences where n is the number of data points on each curve and ai and bi are data values at corresponding points of the two curves being compared. Write an ARM assembly program to read one input data set and compare it against all reference data sets to find out which curve is the closest match to the given input. Your program must include the followings: 1. Store the input data and reference data sets in memory using. 2. Compare the input data with all reference data sets and calculate the error in each case and store the error values in 10 consecutive memory locations. 3. Find the best and worst match and store the set index in two registers r0 and r1 Input set: -100, -43, 5, 20, 5, -15, -60, -148, -268, -340Set 0: -95, -39, 1, 20, 7, -15, -55, -148, -266, -340Set 1: -98, -38, 2, 20, 9, -13, -57, -152, -264, -330Set 2: -105, -40, 5, 21, 6, -14, -63, -150, -260, -333Set 3: -106, -41, 5, 15, 6, -12, -66, -141, -261, -331Set 4: -101, -42, 4, 27, 8, -19, -69, -139, -262, -344Set 5: -99, -43, 5, 20, 4, -17, -61, -144, -269, -341Set 6: -102, -49, 7, 24, 4, -16, -60, -145, -270, -348Set 7: -95, -39, 5, 22, 3, -15, -62, -148, -272, -330Set 8: -96, -35, 9, 19, 5, -14, -58, -149, -272, -335Set 9: -100, -43, 6, 18, 5, -14, -55, -140, -274, -340
