May I know the solutions and answer for this question? Thank you.

4. T The floating-point format to be used in this problem is an 8-bit IEEE 754 normalized format with 1 sign bit, 4 exponent bits, and 3 mantissa bits. It is identical to the 32-bit and 64-bit formats in terms of the meaning of fields and special encodings. The exponent field employs an excess-7coding. The bit fields in a number are (sign, exponent, mantissa). Assume that we use unbiased rounding to the nearest even specified in the IEEE floating point standard. Encode the following numbers in the 8-bit IEEE format: 0.0011011binary 16.0decimal [10 marks] b Describe how the FOUR (4) functional units in data path are [10 marks] interconnected
