Write and test an assembly language program that solves the following straight-l

Question

Write and test an assembly language program that solves the following straight-line equation for y. Generate an integer result as close as possible to the actual answer. Assume variable x is always positive and x is an 8 bit number.
y = m*x + b
The slope (m) is equal to .68 and the offset (b) is equal to 12. Leave the result (y) in accumulator A. Assume value x is in location Val. Note the result will always fit in 8 bits.
Additional Lab. Write and test an assembly language program that solves the following equation for y, where x is an 8 bit number .
y = m*x2 + b

Explanation / Answer

Multiplication is done using addition Here to get the product m*x, add 'm' to itself 'x' times. Then add the result to 'b' Steps Start Get the slope value 'm' Initialise a counter with 'x' Clear a register Add 'm' to the register Decrement counter 'x' If zero, go ahead.... if not zero repeat addition Add 'd' to the product. Given m=0.68 and b=12 MVI A, 0.68 MOV E,A MVI D, 00h LDA memory address MOV C,A LXI H, 0000h DAD D DCR C JNZ repeat addition MOV, A, L MVI B, 12h   ---- give b=12 ADD B HLT Answer is in accumulator
