The objective of this program is to simulate some of the functionalities that a kernel has to manage an operating system. For this purpose, the following functionalities have been developed

• Simulate a Scheduler and a Dispatcher with a defined rules
• Simulate virtual memory manager
• Simulate physical memory manager

All the functionalities have been implement using advanced eficent features, such pointers, memory allocation and multithreading.

The technologies used for this project are as follows:

(back to top)

Is mandatory to have installed C program an the make package. To avoid errors during runtime, use Linux instead Windows. The following examples are for Ubuntu distribution:

• c

  sudo apt install GCC

1. Clone the repo

   git clone https://github.com/iakigarci/KernelSimulator.git

2. Install C packages

   sudo apt install make

3. Compile source files

   make

4. Run the init script. Change the parameters name with the simulation parameters

   ./kernel clockFrequency timerFrequency processGenFrequency

   For example:

   ./kernel 10 10 10

As we have seen in the previous section, the execution of the program has been simplified with a MAKEFILE file. The MAKEFILE parameters are:

OBJS	= kernel.o 
SOURCE	= kernel.c 
HEADER	= definitions.h 
OUT	= kernel.out
CC	 = gcc
FLAGS	 = -g -c -Wall
LFLAGS	 = -lpthread -lm

all: $(OBJS)
	$(CC) -g $(OBJS) -o $(OUT) $(LFLAGS)


kernel.o: kernel.c
	$(CC) $(FLAGS) kernel.c 

queue.o: queue.c
	$(CC) $(FLAGS) queue.c 

thread.o: thread.c
	$(CC) $(FLAGS) thread.c 

mensajes.o: mensajes.c
	$(CC) $(FLAGS) mensajes.c 

clean:
	rm -f $(OBJS) $(OUT)
