c++ - HELP NEEDED...I'M DESPERATE...
- Dragomir Jankovic <jdragomir accesscomm.ca> Feb 14 2002
I need help with my programming assignment and I'm totally clue less. Here's what I need to do: A foreground/background real-time system is one in which tasks are categorized into two sets. The foreground set contains all tasks that are high priority, and the background set contains all tasks that are low priority. Generally the background task or tasks do some non-essential (or non time critical) work like RAM scrubbing, ROM check summing, instruction testing, and so on. An example of a foreground/background system presented in class was the timer interrupt example, where the foreground was the ISR that incremented counter and the background was just a polled loop. Your task in this assignment is to implement a foreground/background system to create a time lock on a safe. The background prints the current time and the unlock time on the screen. The foreground is tied to the PC's timer interrupt and updates a timer variable. The program is to start by requesting the user for the current time and also the unlock time. When it is time to unlock the safe, the PC is to signal the user in some way. (Use your imagination here). Thanks everybody
