- We are provided an FP prototype labeled: IEEE 754-2015 of 15 bits similar to IEEE 754, where the exponent has size 6 bits and fraction has size 8 bits, and 1 MSB for the sign. No guard or round bits are assumed. What is the bias of the system? Find the smallest and largest number that can be represented. Find the new representation of the decimal number you worked with earlier (e.g., the 0.012).The source outputs 0 or 1 in sequences of various lengths. The following is an example: 11111111111111111000000000000000000111111111111111111; Model the source, so you can reduce the total number of bits per sequence.
