Program Code – C++ Templates and Real-Time Systems: A Practical Approach

#include <iostream>
#include <chrono>
#include <thread>

// A templated class for measuring time intervals in a C++ real-time system.
template<typename Precision>
class RealTimeSystemTimer {
public:
    // Starts the timer
    void start() {
        start_time_ = std::chrono::steady_clock::now();
    }

    // Stops the timer and returns the elapsed time in the desired precision.
    Precision stop() {
        auto end_time = std::chrono::steady_clock::now();
        auto elapsed_time = std::chrono::duration_cast<Precision>(end_time - start_time_);
        return elapsed_time;
    }

private:
    std::chrono::steady_clock::time_point start_time_;
};

// Sample real-time task using templated timer
template<typename Precision>
void performRealTimeTask(RealTimeSystemTimer<Precision>& timer) {
    timer.start();
    // Simulate some work that takes time
    std::this_thread::sleep_for(std::chrono::seconds(1));
    auto elapsed_time = timer.stop();
    // Print out the elapsed time in appropriate units
    std::cout << 'Task completed in ' << elapsed_time.count() << ' ';
    if constexpr (std::is_same_v<Precision, std::chrono::microseconds>) {
        std::cout << 'microseconds.';
    } else if constexpr (std::is_same_v<Precision, std::chrono::milliseconds>) {
        std::cout << 'milliseconds.';
    } else if constexpr (std::is_same_v<Precision, std::chrono::seconds>) {
        std::cout << 'seconds.';
    }
    std::cout << std::endl;
}

int main() {
    RealTimeSystemTimer<std::chrono::microseconds> micro_timer;
    performRealTimeTask(micro_timer);

    RealTimeSystemTimer<std::chrono::milliseconds> milli_timer;
    performRealTimeTask(milli_timer);

    RealTimeSystemTimer<std::chrono::seconds> second_timer;
    performRealTimeTask(second_timer);

    return 0;
}

Code Output:

The expected output would be something along these lines (Note: Actual times may vary slightly due to system processing time differences):

Task completed in 1000238 microseconds.
Task completed in 1000 milliseconds.
Task completed in 1 seconds.

Code Explanation:

The provided code showcases the implementation of C++ templates to create a versatile timer class that can be used across real-time systems to measure elapsed time with precision.

1. We begin by including the necessary headers: <iostream> for console output, <chrono> for time measurements, and <thread> to simulate work by putting the thread to sleep.
2. The template class RealTimeSystemTimer takes a typename Precision, which determines the unit of time to measure.
3. Inside the class, the start() method records the current time, saving it to start_time_.
4. The stop() method calculates the elapsed time as the difference between the current time and start_time_, cast to the specified Precision.
5. The private member start_time_ stores the time point at which the timer was started.
6. The performRealTimeTask function is a templated function that takes a reference to a RealTimeSystemTimer object and performs a simulated task. It measures the task duration using the provided timer and prints out the time taken to standard output.
7. The main function demonstrates how to use the RealTimeSystemTimer class with different precision types (microseconds, milliseconds, and seconds). It creates timers for each precision type and performs a real-time task accordingly.
8. The if constexpr blocks check the type of Precision at compile time and output the correct time units. This ensures the printed message matches the precision of the time measurement.
9. Finally, the program returns 0, indicating successful execution.

The core architecture of this program leverages C++ templates to provide a flexible and type-safe way to measure and output time intervals, which is essential for real-time systems where performance and precision are critical.
