Assume a 5-stage MIPS pipeline implementation and consider the following sequence of instructions: addi $s1, $s1, 20
lw $s2, 0($s1)
add $s3, $s1, $s2
add $s4, $s4, $s1
add $s4, $s2, $s5
1. Find all the data dependencies and identify the type of dependency (RAW, WAW, and WAR) for each.
2. What are the final values of $s1, $s2, $s3, $s4; assuming correct execution of the program segment, with initial values of $s1, $s2, $s3, $s4, and $s5 are 1000, 200, 50, 7, and 9 respectively and that memory locations 1000 and 1020 contains the values 300 and 150 respectively.
3. List the hazards assuming your processer does not include either a forwarding unit or a hazard detection unit. What will be the final values of $s1, $s2, $s3, and $s4 in this case as the program is originally written?
4. Add nop instruction(s) to eliminate the hazards you identified in question #3.
5. Now, assume your processor does include full forwarding. Indicate any remaining hazards and add nop instructions to eliminate them.

i want to say d but i could be wrong however it is organized if that could happen..

hope it could

okay, so i know we just goofed around in that chat, but ive been like genuinly depressed, like medically depressed for almost 4 years now. i had my first panic attack when i was 8. i woke my mum up and told her i felt like i was in a dream. like i was a goldfish in a bowl, looking at all these things going on around me and feeling . tiny. wort hless. and i now am now 17 y/o. i still feel those emotions daily. life used to go by so quick.like every day i would wake up and just like want to go back to bed cause i always felt like i was in the wrong place. i guess looking back, i was in the wrong state of mind. i took a expensive like nice trip to whyoming with my grandfather and ha ted it. like idk why. i would have loved it now, but i found myself writing in a journal everyday because i would forget what happened the day before, couldnt remember what i ate for like the previous meal. just my memory left me for the week i was there. worst feeling ive ever experienced.
