Need help with 8086 assembly language
 

I am new to Microprocessor 8086. i should submit this assignment by monday evening. Can anybody help me with this question?

Q1 Write an 8086 assembly language program that will compute:

2.0 * log10 X for x = 0.1, 1.0, 10.0, 100.5, 1000.0, and six other values using a loop. All values are in the single-precision (short real) format.


Kindly help me. I am breaking my head like anything

Re: Need help with 8086 assembly language
 

post the code you are writing. Are you allowed to use the math coprocessor for log and other math functions ?

Re: Need help with 8086 assembly language
 

I would try using the FYL2X instruction, which computes:

st(1) = st(1) * log2(st(0)

Where log2 is logarithm to base 2. You can get from log base 2 to log base 10 with the formula:

log10(x) = log2(x) * log10(2)

.data
short REAL4 0.1,1.0,10.0, 100.5, 1000.0, 400.0, 40.5, 60.6,8.9,10.1
count db 0ah
.code
Lea si, short
Mov cl, count
Loop1:
;moving the element to to ax register
Mov ax, [si]
;Push ax into first position
fld ax
;This instruction is used to find the logarithm of the top most element of the stack
FLDLG2
;Pop the element from the stack
Fstp dl
;displaying the value
Mov ah,02h
Int 21h
Loop Loop1

If u have any queries, just reply me
