A4 Section 1 (1-7) Except 1

[Christopher Rivas]

I am confident that all my answers are right.

Section 1

=======

1. ? --- absolutely no clue how to do it

2. E

3. C

4. B

5. B

6. C

7. D

1. no idea

2. 0.5 (because 2^-1 is 1/2 = 0.5) === .1 in binary

3.  0110.101 ; 1001.011

0110 = 6. +.625 = .101 (http://cs.furman.edu/digitaldomain/more/ch6/dec_frac_to_bin.htm)

for negative numbers you do -7 + 0.375 (take ones complement for negative)

4.do the K-map thing and reduce. (if you want to try it out, use m0, m1, m4, m5, m7)

5. just make a truth table. cross out the combinations where B = 1. that removes 4 combinations from 8. leaving 4 combinations.

6. A+W(I+U-L) ------ U-L = 0. so it's just I*W + A. makes sense. starting point plus index*wordsize.

7. 500/4 = 125. 750/3 = 250. clocks/sec DIV clocks == instructions per second.
