Consider a 32-bit hexadecimal number stored in memory as follows:   Address Value 100 2A 101 C2 102 08 103 1B   1. (2 points) If the machine is big endian and uses 2’s complement representation for integers, write the 32-bit integer number stored at address 100 (you may write the number in hex). 2.  (2 points) If the machine is big endian and the number is an IEEE single-precision floating point value, is the number positive or negative? 3. (4 points)If the machine is big endian and the number is an IEEE single-precision floating point value, determine the decimal equivalent of the number stored at address 100 (you may leave your answer in scientific notation form, as a number times a power of two).

Perform the following binary divisions, assuming unsigned integers: 11111101 ÷ 1011

Suppose we have just found yet another representation for floating point numbers. Using this representation, a 12-bit floating point number has 1 bit for the sign of the number, 4 bits for the exponent and 7 bits for the mantissa, which is normalized as in the Simple Model so that the first digit to the right of the radix points must be a 1.  Numbers in the exponent are in signed 2’s complement representation.  No bias is used and there are no implied bits.  Show the representation for the smallest positive number this machine can represent using the following format.  What decimal number does this equate to?              

Write a MIPS program that always checks the bit 0 of a memory data at address 0x0BF81234. If it is equal to one add nth  and (n+1)th elements of an array and store it to memory address 0x0BF85678 . Suppose $t0  contains the address of the 0th element of an array of 32-bit data and $t1 = n.
