Question

Please answer all the questions! Thank you.

For the following C statement, what would be the corresponding MIPS assembly code? Assume that the variables a, b, c, and d are given and were declared as 32-bit integers a - b - (c + 7)+ d; 1. 2. Show how the value 0xB47CA034 would be arranged in a little-endian and big-endian machine Assume the data is being stored starting with address 0 3. Convert the following base-16 numbers to base-2 a. OxABCD b. Ox1DEF Convert the following base-10 numbers to unsigned base-2 4. a. 35 b. 157 Convert the following signed (two's-complement) base-2 numbers to base-10 5. a. 10011101 b. 00010101 6. Convert the following base-10 numbers to 8-bit signed (two's-complement) base-2 a. 54 b. -49 Assume registers $s0 and $s1 hold the values 0 7. and 0x70000000, respectively What value is assigned to register $tO for the following assembly code? Is the result in $tO the desired result, or has there been overflow? a. add $te, $s«, $s1 What value is assigned to register $tO for the following assembly code? Is the result in $t0 the desired result, or has there been overflow? b. sub $te, $s0, $s1 What value is assigned to register $tO for the following assembly code? Is the result in $tO the desired result, or has there been overflow? c. add $te, $s«, $s1 add $te, $t«, $te

Answer 1

We are allowed to answer 4 sub parts only. So, I answered 3a, 3b, 4a and 4b. Please post accordingly.

Base-16 to base-2
Take each one in base-16 and change it to equivalent 4 bit in base-2

Hex values
A - 1010
B - 1011
C - 1100
D - 1101
E - 1110
F - 1111

3.a) ABCD = 1010 1011 1100 1101
3.b) 1DEF = 0001 1101 1110 1111

Base-10 to unsigned base-2

4.a)

35 217 - remainder -> 1 17 / 2 8-> remainder-> 1 824 -remainder -0 412 2 -remainder-0 22 1-remainder-0 1 2 0-remainder - 1 ผrite remainders from bottom to top Answer100011

4.b)

157 / 2 = 78-> remainder-> 1 78 / 2 = 39-> remainder-> 0 39 / 2 19-> remainder-> 1 19 / 2-9-> remainder-> 1 9 / 2 4-> remainder-> 1 4 / 2 2-> remainder-> 0 2 / 2 1-> remainder-> 0 1 / 2-0-> remainder-> 1 Write remainders from bottom to top Answer10011101
