Assignment Descrip on:
1. Perform a multiplication of two binary numbers (multiplicand 0110 and multiplier 0110) by creating a table to show steps taken, multiplicand register value, multiplier register value and product register value for each iteration by following the steps described in the following document. (Points will be deducted if steps are not shown.)

3. Convert -4563 ten into a 32-bit two's complement binary number.
4. What decimal number does this two's complement binary number represent:
1111 1111 1111 1111 1111 0011 1000 0011 two ?
5. What would the number 18653.4140625 ten be in IEEE 754 single precision floating point format. You need to follow the following steps:
a). Write the above number in binary. (before normalizing it)
b). Write the above number in the normalized format.
c). Compute the biased exponent, and write it in binary.
d). Write its IEEE 754 single precision floating point format in binary, then in hex. (using 8 hex numbers)
6. What would the number -18472.40625 ten be in IEEE 754 single precision floating point format. You need to follow the following steps:
a). Write the above number in binary. (before normalizing it)
b). Write above number in the normalized format.
c). Compute the biased exponent, and write it in binary.
d). Write its IEEE 754 single precision floating point format in binary, then in hex. (using 8 hex numbers)
7. What decimal number would the IEEE 754 single precision floating point number 0xC5A3B760 (this is in hex) be? Write your final answer in scientific notation as m x 10 p where p is an integer.
8. For this problem, assume 5 bits precision. Add two binary numbers,
1.0011 two x 2 -8 and 1.0101 two x 2 -6 by showing the following steps:
Step1: The significand of the number with the lesser exponent is shifted right to match the exponent of the larger number.
Step2: Add the significands. (you can assume that you can carry all digits)
Step3: Normalize the sum, determine whether there is an overflow or an underflow.
Step4: Truncate the sum (using 5 bits precision.)
9. For this problem, assume 5 bits precision. Multiply binary two binary numbers,
1.0011 two x 2 -8 and 1.0101 two x 2 -6 showing the following steps:
Step1: Adding the exponent without bias.
Step2: Multiply the significands. (you can assume that you can carry all digits)
Step3: Normalize the product and check for an overflow or an underflow.
Step4: Truncate the product. (using 5 bits precision.)
10. Add 8.96 ten x 10 10 to 6.87 ten x 10 8, assuming the following two different ways:
a) you have only three significant digits, first with guard (2 digits) and round digits.
b) you have only three significant digits without guard and rounding.
