Question

In a von Neumann architecture, groups of bits have no intrinsic meanings by themselves. What a bit
pattern represents depends entirely on how it is used. Consider the following bit patterns expressed in
hexadecimal notation:

8D28000016

1) What decimal number does the bit pattern represent if it is an integer?

2) What decimal number does the bit pattern represent if it is an unsigned integer?

3) If the bit pattern is in an instruction register, what MIPS instruction will be executed?

4) What decimal number does the bit pattern represent if it is a floating point number? Use the IEEE 754
standard.
