Model the source, so you can reduce the total number of bits per sequence. Discuss the condition for the bit rate reduction. Apply your model to the above sequence. Calculate the compression ratio.

IEEE 754-2008 contains a half precision that is only 16 bits wide. The leftmostbit is still the sign bit, the exponent is 5 bits wide and has a bias of 15, and themantissa is 10 bits long. A hidden 1 is assumed. Write down the bit pattern torepresent -4.573 assuming a version of this format, which uses an excess-16format to store the exponent. Comment on how the range and accuracy of this16-bit floating point format compares to the single precision IEEE 754 standard.

Perform the following additions, assuming 7-bit two's complement binary representation. Show the effect on the status bits (NZVC). Example: Example: Note: that this is a 6-bit example and the questions below are for 7-bit. ex) 101000 + 100000 001000 NZVC 0011 Result was 1001000 but the 1 is carry-out (C-1). Negat ive + Negative should be Negative but positive so overflow (V=1) a) NZVC b) NZVC 1101001 + 1110001 1111111 + 0110101
