Convert the following MIPS assembly code snippet into machine language (hex). Write the code in a memory arrangement (address - content, see Q2 for example) sequentially starting from memory address 0x0000_F000. Show your work step-by-step.

add $s0, $s0, $s1
lw $s0, 0x20($t7)
addi $30, $30, -10
ori $s1, $a0, 100
j 0x400C

Check the exlanation

Explanation:

1) add $s0,$s0,$s1 \rightarrow R-format

opcode rs rt rd shamt function

000000 $s0 $s1 $s0 00000 100000

000000 10000 10001 10000 00000 100000

= 0X42118020

2) lw $s0,0X20($t7)\rightarrow I-format

opcode rs rt offset

100000 $s0 $t7 0X20

100000 10000 01111 0000000000010000

= 0X820F0010

3) addi $s0,$s0,-10 \rightarrow I-format

opcode rs rt offset

001000 $s0 $s0 -10

001000 10000 10000 1111111111110110

= 0X2210FFF6

4) ori $s1,$a0,100 \rightarrow I-format

opcode rs rt offset

001101 $s0 $a0 100

001101 10000 00100 0000000001100100

= 0X36040064

5) j 0X400C \rightarrow J-format

opcode rs

000010 0X400C

000010 0000000000100000000001100

= 0X0800400C

Answer from: Quest

well cos like a ds it doesn't really die out, unlike for example, fifa, they always come out with a new version, so lets say your fifa 18 is charging you to update the teams and stuff, so, if messi were to go to real madrid (never gonna happen) it would switch messi to the other team, until the owners of fifa come out with fifa 19, then the game would eventually stop updating, and back to the ds, it doesn't really stop working after sometime because there's lots of things that it could be used for, and idk if u know what i'm saying, but long story short, samsung, represents the ds, if they still work, and people love them but not the new version, the old version still works, so they don't really force people to buy new phones, get me?

In a heat transfer course, we can derive the equation for the temperature distribution in a flat rectangular plate. in this example, we will look at a plate at steadystate with three sides being held at t1, and one side held at t2. the temperature for any location on the plate, t(x,y), can be calculated by where create a function (prob3_5) that will take inputs of vectors x and y in feet, scalar n, scalars l and w in feet and scalars t1 and t2 in degrees fahrenheit. it will output a matrix t which is the temperature of each x and y locations. t will have the number of columns equal to the number of elements in x and rows equal to the number of elements in y. though this can be done without loops (perhaps more efficiently), your program must use a nested loop.
