        1 8051 Microcontroller Programming using Edsim51
        If you have not already installed Edsim51 simulator, follow these instructions:
        http://www.edsim51.com/installationInstructions.html
        To see a list of all assembly commands, visit the following link:

        To see a list of all characters, visit the following link:
        where each element is an 8-bit number, you are required to write a program
        that computes the sum of products of the elements in each row, i.e. find (a*b)+(c*d) and store the result
        in the memory. The matrix should be added in code memory starting from location 30H as strings
        in ASCII format. To make the computations easier, the elements of the 2x2 matrix 
        a b
        c d
        should be
        stored in a single array as follows: a,b,c,d. Use the following template to put the individual test cases
        in your code memory:
        ORG 0
        SJMP MAIN
        ORG 30H
        N1: DB ”10,04,20,01” ;a=10, b=04, c=20, d=01
        DB 0
        ORG 50H
        MAIN: ...
        1
        To run arithmetic operations on numbers in string format, you have to convert the strings to decimal
        numbers. For instance, the {0x36H,0x34H,0x39H,0x30H} sequence represents the number 64**. Check
        the ASCII table for full details on ASCII representation. Each character in this string (including the
        commas) will be stored in an 8-bit memory location, so for the example given above, the code memory
        starting address 30H will look as follows:
        (30H)=0x31H, (31H)=0x30H, (**H)=0x2cH, (33H)=0x30H, (34H)=0x34H, (35H)=0x2cH,
        (36H)=0x**H, (37H)=0x30H, (38H)=0x2cH, (39H)=0x30H, (3AH)=0x31H.
        You can use the DPTR to point to data in your code memory. The steps that your program needs to
        go through are:
        1. Initialize the DPTR to N1 and initialize any registers that you might need.
        2. loop over the digits one-by-one by increasing DPTR until you reach a comma to find the value of
        the first element a and store it in the register R2.
        3. go through another round of loading the digits one-by-one until you reach a comma to find the
        second element b and store it in register R3.
        4. multiply a and b and save the 16-bit output in locations 50H (MSB) 51H (LSB) in data memory.
        5. repeat the previous process for c and d, and add the result from a*b and store it back in memory
        locations 50H and 51H. Keep in mind that this addition operation should be computed on 16-bit
        values, so you can use what you learned in Assignment 1!
        You can use the comma and null characters, along with conditional jumps to determine if you have
        reached the end of the ASCII representation of an element and jump to the next step in your program.
        Store the 16-bit output result on location 50H(MSB) and 51H(LSB) on the data memory as regular
        hexadecimal numbers. You do not need to convert the output to string! The input numbers are 8 bits
        or less than 256.
        Test your code for the following cases:
        Case1: a=02, b=12, c=15, d=03
        EXPECTED OUTPUT: 50H=00H , 51H=45H (2*12+15*3 = 69 which is 45H in hex system)
        Case2: a=40, b=07, c=36, d=10
        EXPECTED OUTPUT: 50H=02H, 51H=80H (40*07+36*10 = 640 which is 280H in hex system)
        2 Bonus point (10%)
        Save the output in decimal system and in ASCII format, i.e. convert each digit to ASCII representation
        and save them on data memory, starting from 60H. The most significant digit should be stored in 60H.
        You can assume the output is always less than 256 (8 bits).
        Case1: a=02, b=12, c=15, d=03,
        EXPECTED OUTPUT: (50H)=00H, (51H)=45H, (60H)=30H, (61H)=30H, (62H)=34H, (63H)=35H
        (0045 in ASCII is 00003435H)
        Case2: a=40, b=07, c=36, d=10
        EXPECTED OUTPUT: (50H)=02H, (51H)=80H (60H)=30H, (61H)=**H, (62H)=38H, (63H)=30H
        (0280 in ASCII is 00**3830H)
