You will notice that the present exercise is practically identical with theseexamples, only that is uses different numbers.- 'Save As' this Word file in the personalized format indicated in the course pack.- To complete the exercise, you will have to do the following:- Type in text The exercise has 6 sections. Do them in sequence.OBJECTIVEThis exercise has the following objectives:- Review decimal numbers and decimal symbols: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9- Review the decimal carry concept, i.e., when a result is outside the 0 – 9 range- Review 2-digit decimal arithmetic with carry- Prepare the ground for hex arithmetic- Introduce hex numbers and hex symbols: a, b, c, d, e, f- Introduce2-digit hex arithmetic- Introduce 2-digit hex carry as a repeated incrementation- Introduce 2-digit hex arithmetic with carry- Introduce the ‘lost carry’ concept- Introduce MSB carry- Introduce single precision and double precision register conceptsNote: To facilitate understanding, the same numbers are used in both decimal and the hex cases.Dr. Victor Giurgiutiu Page 1 1/15/2019EMCH 367 Fundamentals of Microcontrollers Exercises 3-7PROGRAMYou have to write .asm code to perform the arithmetic operations listed below:i) 8 + 7 = 15 (decimal) using the opcode mnemonics LDAA, LDAB, ABAii) $08 + $07 = $0f (hex) using the opcode mnemonics LDAA, LDAB, ABAiii) 9 + 9 = 18 (decimal) using the opcode mnemonics LDAA, LDAB, ABAiv) $09 + $09 = $12 (hex half carry) using the opcode mnemonics LDAA, ADDAv) $09 + $09 = $12 (hex) using the opcode mnemonics LDAA, LDAB, ABAvi) 12 + 29 = 41 (decimal) using the opcode mnemonics LDAA, LDAB, ABAvii) $0c + $1d = $29 (hex) using the opcode mnemonics LDAA, LDAB, ABAviii) $ff + $01 = $00 (MSB carry) using the opcode mnemonics LDAA, ADDAix) 255 + 1 = 0 (decimal equivalent of a MSB carry) using the opcode mnemonics LDAA, ADDACODING AND EXECUTION Open THRSim11.
