Properties of different architectures

Software architectures are the blueprint of a software system. They consist of all components involved in a system, relations between various components, the environment of operation, and the principle used in designing the software. In other words, software architecture shows the organization of different software structures and helps understand their behavior.

Create an HLA Assembly language program that prompts a number from the user. Create and call a function that calculates the sum of all the numbers from 1 up to the number entered. So for example, a value of 10 would lead to the sum: 1+2+3+4+5+6+7+8+9+10 = 55 In order to receive full credit, you must not use recursion to solve this problem. Instead, you should build an iterative (that is, looping or branching…) function. In order to receive full credit, you must define a function, preserve registers, pass arguments on the run-time stack and return the answer in the register AH. To solve this problem, define a function whose signature is: procedure summing( value : int8 ); @nodisplay; @noframe; Here are some example program dialogues to guide your efforts: Provide a number: 10summing(10) equals 55!Provide a letter: 5summing(5) equals 15!
Problem 1. We usually write numbers in decimal form (or base 10), meaning numbers are composed using 10 different "digits" {0, 1,..., 9). Sometimes though it is useful to write numbers hexadecimal or base 16. Now there are 16 distinct digits that can be used to form numbers: {0, 1, ..., 9, A, B, C, D, E, F) where A, B, C, D, E and F represent digits with values 10, 11, 12, 13, 14 and 15, respectively. So for example, a 3 digit hexadecimal number might be 2B8 = 8 + (B) 16+ (2) 16² = 8+ (11) 16+ (2) 16² = 696. (a) How many 2-digit hexadecimals are there in which the first digit is E or F? Explain your answer in terms of the additive principle (using either events or sets). (b) Explain why your answer to the previous part is correct in terms of the multiplicative principle (using either events or sets). Why do both the additive and multiplicative principles give you the same answer? (c) How many 3-digit hexadecimals start with a letter (A-F) and end with a numeral (0-9)? Explain. (d) How…
Weight 2. A BMI (body mass index) is roughly weight over height square (BMI : Height2 Write Assembly code to calculate average BMI of N students. Relevant data is stored in memory as shown in the example below. Address 10 has the total number of students (N) followed by N weights and heights. Store the computed average BMI at the address 70. For example, if N = 2, the memory contents will be as follows: 0 1 2 |3 | 4 |5 6 10 02 96 05 5A | 06 There are 2 records. Weight and height of the 1s person is 96 and 05 respectively. Similarly, 5A and 06 are the weight and height of the second person. Assume decimal points are ignored and the average will be a rounded integer value. All divisions are integer divisions as well. Please use the Instruction Set of the simulator discussed in class. (http://www.softwareforeducation.com/sms32v50/sms32v50_manual/245-IsetSummary.htm)

In the study of formal languages state-transition diagrams are often usedto visualize changes in a machine’s configuration as it acts on input. To visualize amachine’s configuration think of its parts: Commonly a finite set of states, a finiteinput alphabet Σ, Perhaps storage devices (a stack, input/output tapes). The states arepictured as named circles sometimes decorated with symbols to denote special states,e.g. start and final states. Changes in configuration are denoted by labeled edges andperhaps changes in storage.1. Describe how edges are labeled and their meaning for finite state machines.2. Describe how edges are labeled and their meaning for pushdown automata.3. Describe how edges are labeled and their meaning for Turing machines.
20. Suppose a computer program has been initialized such that the following sets have been stored for use in any algorithm: A = {1, 2, 3, ..., 45}B = {-7, -6, -5, ..., 27} Consider the following algorithm, which represents one part of the whole computer program (comments may occur after the # symbol on any line and are not used in computations): #Part 1: computes A - B and its cardinality AminusB = set()for element in A: # this line runs through every element in A if not(element in B): #A - B is the set of elements that are in A and are not in B AminusB.add(element) # Add to AminusB every element in A if the element is also not in B n = len(AminusB) #len() returns the number of elements in the arrayprint(n) What value is printed as a result of executing this algorithm?
using Python programming language. The Towers of Hanoi is a classic puzzle that consists of 3 towers, and n disks of different sizes that can slide onto any tower. The puzzle starts with the disks sorted in ascending order of size from top to bottom. It has the following constraints:a. Only one disk can be moved at a time.b. A disk can only be moved from the top of one tower to another tower.c. A disk can only be placed on top of a larger disk. Write a pseudo-code.
