All programs are implemented in C language. Assignment details Topic: CPU Scheduling, FIFOs and Signals This topic will involve some application program developments using CPU scheduling, FIFOs and Signal concepts. You are required to develop two programs, namely Topic1_Prg_1 and Topic1_Prg_2. The requirements of these two programs are (1) Topic1_Prg_1: You are required to use CPU scheduling and FIFOs in your program. Your program is to simulate CPU scheduling by applying Shortestremaining-time-first algorithm (SRTF). Your program is required to measure average waiting time and turnaround time in your CUP scheduling. When CPU scheduling is completed, your program is required to define a FIFOs and write these average waiting time and turnaround time to CPU memory through the FIFOs. The input data involving the CPU scheduling are as follows: Process ID Arrive time Bust time 1 8 10 2 10 3 3 14 7 4 9 5 5 16 4 6 21 6 7 26 2 (2) Topic1_Prg_2: After the programming of Topic1_Prg_1, your program is required to read the average waiting time and turnaround time from the memory through the FIFOs as defined in the Topic1_Prg_1. Then, your program is required to write those read data to a text file named "output.txt". You need to set up your own signal (SIGUSR1 or SIGUSR2) to watch the "output_topic1.txt" and give a notification when the writing "output_topic1.txt" is completed. After scheduling, the program will print out the average waiting time and turnaround time to your PC's console. The format of print-out is as follows: Process ID Average Waiting Time Turnaround Time 1 2 3 … … … You are required to write a report to summarise your observation.
