3. (3 pts.) Draw a simple 4-element block diagram of a computer and briefly describe each of the elements. 4. Put your answers for this question on the continuation sheet(s). We studied the IEEE Std 754 binary32 floating-point format and postulated the existence of a binary16 floating-point format that was similar to binary 32 but smaller. This ficticious binary 16 has a sign bit, a 6-bit biased exponent, where bias =26-1-1= 31, and a 9-bit fraction with an implied leading 1 bit. $ C 1 +6 bits - 9 bits (a) (5 pts.) Show the binary16 hex representation for the floating-point decimal value -2.25 (b) (5 pts.) Show the Boating-point decimal value for the binary 16 hex representation Ox44E0 LEAVE THIS AREA BLANK Put your answers on the next 1 or 2 pages. N
