SPO600

 I don't no why it would not show up (I just came back to blog more) Project Plan This is going to be a break down of my plan for SPO600 final project, for this project we are going to be doing a proof of concept to test i func procedures " The goal for this project is to produce a proof-of-concept tool that will take code that meets specific conditions and automatically build it with ifunc capability to select between multiple, autovectorized versions of a function, to take advantage of the best SIMD implementation available on the CPU on which the code is running. " (Chris Tyler) To test the solution some code has been provided  https://github.com/ctyler/spo600-fall2022-project-test-code For this task I am going to be using JSnode for the code and plan to write it on VS code or Atom. I am using these languages as I am familiar with that set up. We have some limitations to the project which are the following: This tool only operates on aarch64 systems There are three ta...

 For the lab we are tasked with mongering and making a prediction of the relative performance of each scaling algorithm. Using both aarch64 and x86 we first need to unpack the code using tar. I started with aarch64 first.

 For this lab we were tasked with doing the same loop problem from the aarch64. How ever me being the genius I am I tried to switch to the x86 well still on the Israel server not even thinking to switch to the Portugal one. So After just getting that sorted out I can now attempt to build the code.  Also unpacking the file was needed again as you can see here:  I have so far got it loop the hello world out but just need to change it to loop for the ascii message and print the number here is my code so far min = 0                         /* starting value for the loop index; note that this is a symbol (constant), not a variable */ max = 10                        /* loop exits when the index hits this number (loop condition is i<max) */ _start:     mov     $min,%r15           /* loop index */ lo...

 For this lab we are tasked with editing some code provided by the prof Chris Tyler. We needed to create a loop in order for the word loop to be printed 30 times. This lab was extremly hard for me as I had to re learn a lot of the commands and it was very time consuming, but was cool to learn. For starters I did not know that to extract the package and to make files was confusing. One of the most time consuming parts was trying to run the code each time and debug it. 1. Review, build, and run the aarch64 assembly language programs. Take a look at the code using  objdump -d  objectfile  and compare it to the source code. First we had to extract the package  tar zxvf fileNameHere.tgz here is the source code provided for the aarch64 task For the aarch64 part of this lab we had to get the word "loop #" to loop ten times and show the count s it looped. This task was seemed easy but became very hard, trying to understand syntax and how the compiler worked. For a long...

 Now that was a lot of code! as you can see I have had to separate the code into three posts. This program works by first executing two sub routines that are going to initialize the memory (init, loop)  which will set the game state and the loop is going to call the subroutines of the program and execute them in order before looping back and and repeating. I like the way this program is broken down into different sub routines like functions it makes it easier to follow. I Changed the controls from the original and also added a way to add a second value called SnakeLengthTwo it increased the size by double but the issue was that when it was added is that from where the last apple was that was eaten the tail value stays at that location in memory and the snake moves but just grows at a rapid rate. updateSnake:   ldx snakeLength   ldx snakeLengthTwo //this will make the snake tail stay at the same spot   dex   txa updateloop:   lda snakeHeadL,x   sta...

 For this lab we were tasked with creating a simple game or using open source code and adding some of our own code to it. The lab is based on the 6502 assembler and is written in assembly language, for this task I found a classic game of snake that is written in assembly and it is a little complex but I was able to follow it and make a few changes.  Green highlight is my code and edits, Blue code is important to user input and movements Source material:  https://skilldrick.github.io/easy6502/#snake THE CODE ;  ___           _        __ ___  __ ___ ; / __|_ _  __ _| |_____ / /| __|/  \_  ) ; \__ \ ' \/ _` | / / -_) _ \__ \ () / / ; |___/_||_\__,_|_\_\___\___/___/\__/___| ; Change direction: W A S D define appleL         $00 ; screen location of apple, low byte define appleH         $01 ; screen location of apple, high byte define snakeHeadL  ...
