Program Code – Real-Time System Integration Techniques Using C++

#include <iostream>
#include <thread>
#include <mutex>
#include <chrono>
#include <queue>
#include <condition_variable>

// A mock function to simulate data processing
void process_data(int data) {
    // Simulate some complex processing on the data
    std::this_thread::sleep_for(std::chrono::milliseconds(100));
    std::cout << 'Processed data: ' << data << std::endl;
}

// Thread-safe queue class
template<typename T>
class SafeQueue {
private:
    std::queue<T> queue;
    std::mutex mut;
    std::condition_variable data_cond;

public:
    SafeQueue() {}

    void push(T value) {
        std::lock_guard<std::mutex> lk(mut);
        queue.push(value);
        data_cond.notify_one();
    }

    void wait_and_pop(T& value) {
        std::unique_lock<std::mutex> lk(mut);
        data_cond.wait(lk, [this] {return !queue.empty(); });
        value = queue.front();
        queue.pop();
    }
};

// Data producer
void producer(SafeQueue<int>& queue) {
    for (int i = 0; i < 10; ++i) {
        queue.push(i);
        std::this_thread::sleep_for(std::chrono::seconds(1));
    }
}

// Data consumer
void consumer(SafeQueue<int>& queue) {
    for (int i = 0; i < 10; ++i) {
        int data;
        queue.wait_and_pop(data);
        process_data(data);
    }
}

int main() {
    SafeQueue<int> queue;

    std::thread producer_thread(producer, std::ref(queue));
    std::thread consumer_thread(consumer, std::ref(queue));

    producer_thread.join();
    consumer_thread.join();

    return 0;
}

Code Output:

Processed data: 0
Processed data: 1
Processed data: 2
Processed data: 3
Processed data: 4
Processed data: 5
Processed data: 6
Processed data: 7
Processed data: 8
Processed data: 9

Code Explanation:

The given C++ program demonstrates a simple real-time system integration technique. It does this by establishing a producer-consumer scenario using threads, a thread-safe queue, mutexes, and condition variables. Here’s a step-by-step breakdown:

• Include Headers: We include necessary headers such as <iostream> for console I/O, <thread> for threading support, <mutex> for mutual exclusion, <chrono> for time-related functions, <queue> for the queue data structure, and <condition_variable> for condition variable support.
• process_data Function: A function to simulate processing of data that simply sleeps for a short duration and then prints the processed data.
• SafeQueue Class Template:
  • A queue wrapper that ensures thread safety by using a mutex to protect shared data and a condition variable to synchronize thread operations.
  • The push method locks the mutex, adds an item to the queue, and then signals one waiting thread.
  • The wait_and_pop method locks the mutex and then waits for the queue to become non-empty, after which it retrieves and pops an item from the queue.
• producer Function: This function simulates a data producer that pushes integers from 0 to 9 onto the queue, simulating a delay between each push to mimic real-time data production.
• consumer Function: This function represents a data consumer that waits for data to be available in the queue, then consumes and processes it by calling the process_data function.
• main Function:
  • A SafeQueue instance is created for integers.
  • Two threads are spawned— one for the producer and one for the consumer.
  • Both threads are then joined to the main thread to ensure that the program waits for their completion before exiting.

The program exhibits a fundamental approach to real-time system integration by employing concurrency mechanisms to ensure that data can be safely exchanged between different parts of a system, such as between a data provider and a consumer. It mimics a sophisticated environment where data is produced and consumed in real-time, necessitating the use of synchronization techniques to ensure consistency and integrity.
