Lab 4 - Part 2 x86_64

-

 Hello everyone in this lab we are test some piece of code to make the loop in the AArch64 system and lets start with the base code which is given by Chris Tyler.

So in this lab we just need to work with the AArch64 system and x86_64 and make use more familiar with this ssh system that is call israel and portugal which are two different system working on AArch64 an x86-64.

So for the first time we need to make the code that will run on the x86_64 system which is going to print the loop from 0 to 9 and the base was given to us by Chris Tyler.

So making it we have to useful but dugging is was hard enough to find one single error. so starting with the error like when i start searching i am not able to figure out which increments and loop skiping variables are going to used and then i read some notes and watch the lecture again to find it out.

Now for 0 to 30 we just need to change some thing like add ,max values and add some varibale to balance it out. Like the max value should be like 31 so it start from 0 till 30 and has some more handler.

IFUNC What is IFUNC? With the aid of a resolver function that was also written by the developer, numerous implementations of a particular function can be created using the GNU indirect function support (IFUNC) feature of the GNU toolchain. During early startup, the dynamic loader calls the resolver function to determine which implementation the application will use. Once a decision on implementation is made, it cannot be modified for the duration of the procedure. How to use it? As you can see, there are already a few limitations on how IFUNC can be used.                                                             It is t he implementations and the resolver must both be defined in the same translation unit. functions that cannot be weakly specified.    Since the resolution of an IFUNC might occur very early in the dynamic loader startup process, especially if -Wl,z,now is used to generate the application, the limitations are actually stricter than this (requires all symbols be resolved

 We spoke about how to analyse sound and programmatically scale sound input before we started the lab. The process of sound analysis is not particularly unique. Integer and floating point (decimal) numbers used to represent sound input are parsed to perform analysis. Additionally, changing the level simply involves performing an arithmetic operation on each integer contained in the sound sample. And that was the lab's main objective. The objective was not without risk, though. The easiest or most naive way was to perform the procedure by looping through all the numbers. This was a lengthy and ineffective method, though, when done on a mobile device. Because the CPU executes this repeating operation each time the user changes the volume, this drains the battery. Our task was to come up with a more effective technique to accomplish this. We have sound samples in the lab that are exclusively represented by random numbers between -65,536 and 65,536, or the range. Why those strange digi

 In this lab we need to find how much is time need to complete the process of code. So here we need to find the number of the cycles that are need to complete the process of one line of code to processed. So as shown in photo  The load accumulator need two cycle to complete the process and only one time this code is run. After that store accumulator will run and same as load accumulator it will run ones with two cycle. After all the function will be run as shown above but when the loop will be there t process will be change there are 256 bytes in one page and there are total 4 page to this will run 12 time and as shown above it will be executed.  And the time will be 5935us when there was 1Mhz clock speed is there. To change the speed we need to make change like we need to change the loop of pages to only one  which can change the part of time but I am not able to make that one.
