- Implementing matrix addition is pretty simple; see the program below. However, the given addition function matrix_add_double() does not run at full speed. On the instructors computer, which has 16GB of RAM, the program below shows that the call to matrix_add_double takes 38571 ms, while another, better implementation achieves the same result in 3794.7ms, which is 10.2 times faster! Your job for this exercise is: • to explain what in the Operating System and/or CPU and/or other part of the system makes the implementation below go so slowly. • to fix the code to achieve full speed. Hint: There are two reasons why the code runs slowly. The one reason is related to how virtual addresses get translated to physical addresses, the other reasons is related to another effect in the hardware. Only the performance for the matrix_add_double function() counts for your exam results. You can leave the other parts of the code untouched, but you may also change them.…The Dirtcheap Software Company is planning to produce an assembler for a computer with a 48-bit word. To keep costs down, the project manager, Dr. Scrooge, has decided to limit the length of allowed symbols so that each symbol can be stored in a single word. Scrooge has declared that symbols may consist only of letters, except the letter Q, which is forbidden (to demonstrate their concern for efficiency to the custo- mers). What is the maximum length of a symbol? Describe your encoding scheme.To better understand the concept of recursion, let’s look at an example that’s quite familiar to computerusers—the recursive definition of a file-system directory on a computer. A computer normally stores related filesin a directory (also called a folder). A directory can be empty, can contain files and/or can contain other directories,usually referred to as subdirectories. Each of these subdirectories, in turn, may also contain both files anddirectories. If we want to list each file in a directory (including all the files in the directory’s subdirectories), weneed to create a function that first lists the initial directory’s files, then makes recursive calls to list the files in eachof that directory’s subdirectories. The base case occurs when a directory is reached that does not contain anysubdirectories. At this point, all the files in the original directory have been listed, and no further recursion isnecessary. Write a print_directory function that recursively walks through the…
- Write a C program that does a large number of references to elements of two-dimensioned arrays, using only subscripting. Write a second program that does the same operations but uses pointers and pointer arithmetic for the storage-mapping function to do the array references. Compare the time efficiency of the two programs. Which of the two programs is likely to be more reliable? Why?We often used slicing of arrays as examples when we were learning recursion. These are excellent examples for learners, but in the real world they have a significant problem. What is the problem? Enter your answer here Explain an easy trick that we can use to get around this problem, while still retaining the recursive nature of our solution. Enter your answer hereFor those who are unfamiliar, what exactly is a "program slice"? We need to talk about segmenting programs both statically and dynamically.
- Answer In python only Tom explored a binary number system and found that it is much easier to perform smart tasks such as AND, XOR or bit shift on non-negative integers, while it is much more complex to perform arithmetic. After playing binary options for a while, Chef developed an exciting algorithm to add two non-bad numbers A and B: Now Chef wonders how fast this algorithm is. Considering the initial values of AA and BB (binary representation), you need to help him calculate the times when the algorithm loop is repeated. Input 3 100010 0 0 100010 11100 1010 Output 0 1 3Finding N! by using Recursion! Note: please have comments on each line of the code! Assignment for Computer Architecture You are to write a program in MIPS that computes N! using recursion. Remember N! is the product of all the numbers from 1 to N inclusive, that is 1 x 2 x 3 x (N – 1) x N. It is defined as 1 for N = 0 and is undefined for values less than 0. The programs first requests the user to input the value of N (display a prompt first so the user knows what to do). If the input value is less than 0, the program is to display “N! undefined for values less than 0” and then requests the user to input the value of N again. If the value input is non-negative, it is to compute N! using a recursive function, that is one that calls itself. You are to have your name, the assignment number, and a brief description of the program in comments at the top of your program. Since this is an assembly language program, I expect to see comments on almost every line of code in the program. Also…Hello. Please answer the attached RISC-V question correctly by converting the given C code to RISC-V. There is already some RISC-V code written, and you have to complete the rest of it based on the given C code. The code must be recursive and have comments that show what's happening. *If you correctly convert the code and make sure that it is recursive and has comments, I will give you a thumbs up. Thank you.
- There are many algorithms presented in this text that would lend themselves to beincluded as subprograms in the utils.asm file. Implement some or all of the followinginto the utils.asm file, properly documenting them, and include programs to test them.a. NOR subprogram - take two input parameters, and return the NOR operation onthose two parameter.b. NAND- take two input parameters, and return the NAND operation on those twoparameter.c. NOT- take one input parameters, and return the NOT operation on that parameter.d. Mult4 - take an input parameter, and return that parameter multiplied by 4using only shift and add operations.e. Mult10 - take an input parameter, and return that parameter multiplied by 10using only shift and add operations.f. Swap- take two input parameters, swap them using only the XOR operation.g. RightCircularShift - take an input parameter, and return two values. The firstis the value that has been shifted 1 bit using a right circular shift, and the second isthe…Make a BST implementation that uses three arrays to represent the BST: an array for keys, an array for left and right array indices, and an array for right array indices. The maximum size supplied in the constructor should be preallocated to the arrays. Compare the performance of your programme to that of the typical implementation.please use python language instruction- 1. Read the code from line 123 to line 137. This is the basically the selection. Remember how we talk about there are certain things about controlling population? Please explain how we make sure that the population, when going through a selection, does not shrink over generation. You may simply explain this as comments in a Python file as opposed to in a Word file:. Note that the code from line 123 to line 137 is divided into two small blocks. Use that as 2. The code we've just examined has one functionality of selection. So, we really should wrap that into one function nanied 'select'. Note that in this file there is no class named 'Population'. So, you should make this function a static method that belongs to the class named 'Individual', or a simple function that resides outside the class named 'Individual'. Please think about what the inputs and output of this function are before you start coding. Once you have created the…
