Question
Write an ARM assembly program ieee.s to assign the hexadecimal equivalent for IEEE 32 bit
format of a decimal number in variable ie and extract the sign bit, the exponents and the
fraction part in three separate functions (procedures) and shift the bits so that the registers
have their actual value and store them in variables s, ex, fr. (Review floating point
conversions and formats before doing this program)
You will run the program step by step, observe and make sure the program runs for different
test cases. (40 points)
Example:
-3.75 has the IEEE 32-bit format as below
11000000011100000000000000000000
The hex equivalent will be 0xc0700000; store that in variable ie.
Then extract sign in R1, exponent in R2 and fraction in R3 using three functions
Procedure 1
R1= 10000000000000000000000000000000
After shifting R1=00000000000000000000000000000001 = 110 Or 0x1
Procedure 2
R2= 01000000000000000000000000000000
After shifting R2= 00000000000000000000000010000000 = 12810 or 0x80
Procedure 3
R3= 00000000011100000000000000000000 = 0x700000 (No shifting required for R3 )
In main
Store value in R1 to variable s, R2 in variable ex and R3 in Variable fr.
