The Test-and-Set instruction is used in hardware to achieve synchronization. It can be defined in the following way: function Test-and-Set (var target: boolean): boolean; begin Test-and-Set:= target; target := true; end; Now show how the Test-and-Set instruction can be used to protect a critical region and hence achieve mutual exclusion (do not worry about satisfying the bounded waiting condition).

But to roll and smoke a cigarette, the smoker needs three ingredients: tobacco, paper and matches. One of the smoker processes has paper, another has tobacco and the third has the matches. The agent has an infinite supply of all three materials. The agent places two of the ingredients on the table. The smoker who has the remaining ingredient then makes and smokes a cigarette, signaling the agent on completion. The agent then puts out another two of the three ingredients, and the cycle repeats. Given below is a solution to the Cigarette-Smokers Problem. Give initial conditions for the semaphores as well as plausible values for the variables i & j and r & s, such that the agent and smokers are synchronized. Write a couple of sentences on why these initial conditions are necessary and sufficient. Solution: var a: array [0..2] of semaphore (initial condition =…arrow_forward
- Level-0 Diagram for this: A customer sends in an order form containing details of their order and their membership number. A check is made to verify that they are a member. When their order is verified, a check is made to validate that the items ordered are produced by the company. Next, the valid order is used to update the daily order file, and then used to create a shipping list and invoice, which are sent on to the Order Fulfilment System.arrow_forwardIn this assignment, you will use all of the graphics commands you have learned to create an animated scene. Your program should have a clear theme and tell a story. You may pick any school-appropriate theme that you like. The program must include a minimum of: 5 circles 5 polygons 5 line commands 2 for loops 1 global variable You may wish to use the standard code for simplegui graphics below: import simplegui def draw_handler(canvas): frame = simplegui.create_frame('Testing', 600, 600) frame.set_canvas_background("Black") frame.set_draw_handler(draw_handler) frame.start() Submit Your Code After you write your code here in the programming environment, you will check it and submit it as usual. However, the grader will only perform basic checks against some requirements. If your code passes, you should submit your work, and your teacher will manually grade your submitted work using a rubric.arrow_forward1.

- What is the goal of using a chart in excel, and how is a chart useful and what is the goal of using sparklines in excel, and how are sparklines useful?arrow_forwardProve for each pair of expression f(n) and g(n) whether f(n) is big O, little o Ω,ω or Θ of g(n). Use limits to find these. For each case it is possible that more than one of these conditions is satisfied:1. f(n) =log(n2^n), g(n) = log(sqrt(n)2^(n^2))2. f(n) =nsqrt(n) +log(n^n), g(n) =n + sqrt(n)lognarrow_forwardNeed this expression solved for mu. This can be done using a symbolic toolbox, however it needs to end up being mu = function (theta, m, L, g). If using MATLAB or something similar, run the code to make sure it works.arrow_forward
