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) {

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(); });

// Data producer

// Data consumer
void consumer(SafeQueue<int>& queue) {

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.
- A
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.
