(3e) Test-and-Set. 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).

Consider a system with three smoker processes and one agent process. Each smoker
continuously rolls a cigarette and then smokes it. 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 =…

- 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.
