Course Project stage 3 part 2: Last post

Well, as the end of the course and semester approaches, so does my last blog for SPO600.

Last post I dive into the method, "bt_find_func" and identified "cmp" that take most resources.


"cmp w22, #0x0" is used to check for zero in register. I originally wanted to find a way to improve "cmp", dead end there.

Then I change my approach and look into the line before "cmp" which is the "if" statement "(depth-- == 0 || delta >= cyclic_size)", also dead end there.

At this point I know I lack the knowledge to successfully optimize "xz Utils", but I must continue research.


(After 1 day...)


I try to understand some of the professor's lectures about stage 3, also I read some of previous student's post in hoping those can help me understand but I am stuck........

Unfortunately, what I have so far is my limit. Maybe in the future I'll learn how to successfully optimize xz Utils, but for now this would conclude my post for SPO600.

Thank you for reading my posts and please stay healthy.

Return from MIA

Ok, it has been more than half a month since my list post. Why I waited so long? Well, it is completely my fault. For the past month my focus was completely on another class in the same semester as this one. I wasn't doing well in that course, so I was trying to shift my balance toward that course and end up with a poor time management result. BUT!! I have shift my attention back to this course and hopefully with the little time left in this course can I catch up with my other classmate without hitting too much penalties. Last post I mentioned that I seeked help from my professor and I was successful in filling some of my knowledge gaps. For the past few days I use my knowledge trying to fully understand some of the code examples provided for students to understand 6502 coding. Currently still in progress. I have scheduled another extra help time slot with professor in a few day, hopefully I can finish my self study of the code example and bring only questions that need

Course Project Stage 2 Introduction

Issue has arrived!! Since I pushed my work for SPO600 till today because of my other focuses in other school works (my own fault), an issue has arrived. Today unexpectedly all the school remote machine rejected all my attempt for connection. A few days ago, there was an email send from the professor talking about all the machines are going through mass restarts on Friday. We were told to expect Aarchie and Israel might continue to be unavailable even after restart because the restart is done remotely. But today I wasn't able to connection to Bbetty and Xerxes as well which are the only other machines I have access to. Now, I have no choice but resort to one of my last resorts. I'll have to enable the windows subsystem for Linux on my laptop and work from there. Since I don't use my laptop for anything other than school work, this will keep my bench marking and profiling errors to minimum. My laptop system type is 64-bit OS, this would cover at least the Aarch64 part of
