![2. Explain how the following ARM program can be used to determine whether a computer is big- endian or little-endian: MOV R0, #100 LDR R1, -0xABCD876 STR R1, [RO] LDRB R2, [R0, #1] R1-0xABCD876](http://img.homeworklib.com/questions/cb6dd250-3f90-11eb-9106-8335dd74acc0.png?x-oss-process=image/resize,w_560)
indicate what each line of code means
Homework Answers
Line 1 says that Move Value #100 decimal value in Register R0
Load Address Value 0xABCD876 in R1
Now Store the value at R0 in the address at R1
Load R2 with the value at R0 with signed bit #1
When we store the value at R1 it will show big or liitle endian
