AUTO - Another Unuseful Track simulatOr
---------------------------------------
 
by Marco Dallera and Marco Fiocca, 2001
 
---------------------------------------
 
This project was done as a Lab assignment during the course of
"Informatica Industriale" at the University of Pavia, Italy.
 
It simulates a race between cars under a set of 4 tracks.
 
The authors provided also some pages that describes the application
(auto-rel.ps, in italian).
 
To run the application, just compile it and call "x auto th" where tn is
the track number (0 to 4).
 
Since the control algorithm is quite complex, you need a quite powerful
machine. If you get an exception 8 (WCET violation), you need a faster PC.
You can anyway run the application making "auto2", that uses RR instead of
EDF or CBS, or "auto3", that uses the EDFACT Module (you need yo copy
the edfact.c and edfact.h files in the application directory to do that).
 
To be run, the application needs to be compiled with the
#define MAX_CAB set to a number greater than 20 (see include/modules/cabs.h).
 
The control algorithm of the cars is not yet perfect, and if you look to
the race for a long time, sometimes some cars go in the wrong direction.
If you find a better algorithm, send me a patch :-)
 
The code you can find in this directory is the original code of the
students except for the MAX_CAB test into main(), and for the idle time
monitor (that I took from the jumpball example) that can be useful to know
when the system is overloaded. For example, on my PC there is idle time until
the system has 9 cars. The tenth make the PC overloaded until one of them
crashes :-).
 
Finally note that the WCET and PERIODS specified by the authors are not so
correct, and with this setting you can run 8 cars maximum before crashing the
system.
 
Have a nice race...

PS: Sometimes on my portable the demo crashes. I wonder why!... If someone
finds why, please tell me, I will patch it...

PING PONG
==============
AUTHORS : Kabilan Sukumar
Rajenish Kumar Jain
Deepaknath T K
 
Project work for shark part of the Operating Systems Course.
 
Changes made:
==============
1. A new function , BYTE getKeyFlag(void) ,added into the file /drivers/char/keyb.c. This returns the keyFlag which stores the scan code to the key pressed. This was used to make the movement of the bat smooth. Normal use of keys did not work because the interrupt rate was not adjustable.
 
2. The function was added into the include file /include/drivers/keyb.h
 
Instructions:
==============
1. Copy the file Keyb.c to /drivers/char/
2. Copy the file keyb.h to /include/drivers/
3. Recompile the kernel by typing MAKE in c:/shark.
4. Copy the the folder pingpong_proj to c:/shark/demos.
5. Type MAKE to compile the proj.
6. Type X demo to run the game. Then follow the instructions given.
7. ENJOY the GAME.

HELP FILE FOR HUNGRY SNAKES GAME..
 
AIM :
 
TO EAT THE LARGEST NO OF FRUITS
WITHOUT HITTING ANY STONES ,WALL AND THE OTHER SNAKE.
IT SHOULD NOT CROSS ITS OWN BODY ALSO.
 
FRUITS :
 
THEY ARE CIRCULAR IN SHAPE AND APPEAR IN
RANDOM COLOURS AT RANDOM POSITIONS FOR
RANDOM TIME.
ON PASSING OVER THE SNAKES ,U SCORE BONUS
1000 POINTS.
 
STONES:
 
THEY ARE RED COLORED RECTANGULAR BRICKS.
IF THE SNAKE HITS THEM IT DIES.
 
BUGS :
THE BOUNDARY WALLS MAY NOT BE OF EXACT PRECISION
DURING CRASHES.
THE TWO SNAKES DIE ONLY WHEN THE SNAKE PIERCES TO
SOME EXTENT INSIDE THE OTHER SNAKE.
THE FRUIT MIGHT APPEAR ON THE SNAKE BODY !! (OOPS)
AFTER THE SNAKE HAD EATEN A FRUIT, A HOLE IS PRODUCED
ON THE SNAKES BODY..(...:O)
 
HOW TO PLAY :
THIS A 1 OR 2 PLAYER GAME, +
U CAN CHOOSE THE MODE WHILE ENTERING,
SPACE BAR :START GAME
ESC :EXIT GAME

From: kailash <sharma@sssup.it>
To: pj@gandalf.sssup.it
Subject: Project Sumbmission: Ship_v1
 
Dear Sir,
 
Please find attached our project on SHIP-BULLET-ASTEROID simulation game.
source file : Ship_v1.c
object file : Ship_v1.o
Zip file: Ship_v1.zip (also contains above two files)
 
Features:
1. The program creates a ship. The motion of the ship can be controlled
(left, right, up and down).
2. The ship can fire bullets on pressing space bar (i.e. creates a new task
for each bullet).
3. Asteroids are generated at random (each asteroid is a new task).
4. Asteroids travel from right to left. When an asteroid reaches the left
most boundary, the task asteroid is destroyed.
5. Bullets travel from left to right. When a bullet reaches the right most
boundary, the task bullet is destroyed.
6. At any point of time there are MAX_A = 35 asteroid tasks and MAX_B = 35
bullet tasks on the screen.
7. In this way the creation of asteroid and bullet task is continuous (till
they do not reach the max value).
8. Bullets destroy the asteroids, while asteroids tries to destroy the ship.
9. Everytime an asteroid is destroyed, the player gets a point and it is
displayed on the screen.
10. When an asteroid hits the ship, the game_finish flag is set and all
tasks are destroyed.
11. Once all tasks are destroyed, the game is over.
 
The speed of bullet and asteroid can be controlled by setting the variable
bullet_delay and asteroid_delay.
 
Future work:
It is desirable to have a menu controlled GUI to play SHIP - ASTEROIDS game.
This version of our program does not
support this functionality. We will soon work on this and send you the next
version of this game, that will
be Menu driven.

source file : Ship_v1.c
object file : Ship_v1.o
 
##############
# Features #
##############
1. The program creates a ship. The motion of the ship can be controlled (left, right, up and down).
2. The ship can fire bullets on pressing space bar (i.e. creates a new task for each bullet).
3. Asteroids are generated at random (each asteroid is a new task).
4. Asteroids travel from right to left. When an asteroid reaches the left most boundary, the task asteroid is destroyed.
5. Bullets travel from left to right. When a bullet reaches the right most boundary, the task bullet is destroyed.
6. At any point of time there are MAX_A = 35 asteroid tasks and MAX_B = 35 bullet tasks on the screen.
7. In this way the creation of asteroid and bullet task is continuous (till they do not reach the max value).
8. Bullets destroy the asteroids, while asteroids tries to destroy the ship.
9. Everytime an asteroid is destroyed, the player gets a point and it is displayed on the screen.
10.When an asteroid hits the ship, the game_finish flag is set and all tasks are destroyed.
11.Once all tasks are destroyed, the game is over.
 
The speed of bullet and asteroid can be controlled by setting the variable bullet_delay and asteroid_delay.

# Future work #
###############
It is desirable to have a menu controlled GUI to play SHIP - ASTEROIDS game. This version of our program does not
support this functionality. We will soon work on this and send you the next version of this game, that will
be Menu driven.

System initialization file
 
This file contains the 2 functions needed to initialize the system.
 
These functions register the following levels:
 
an EDF (Earliest Deadline First) level
a RR (Round Robin) level
a CBS (Costant Bandwidth Server) level
a Dummy level
 
It can accept these task models:
 
HARD_TASK_MODEL (wcet+mit) at level 0
SOFT_TASK_MODEL (met, period) at level 1
NRT_TASK_MODEL at level 2
 
This file is similar to the configuration of kernel/init/hartik3.c
 
TICK is set to 0 (one-shot timer is used)

Description of Game:
 
We had tried to make a game in which from has to jump on leaves flowing through the water, go to the lowest level and then come up. There is enemy of a from moving around on land. Enemy will try to kill the frog by touching it when frog is on the land. There is timer, after the expiration of timer the game will finish.
 
Details:
 
Tasks used:
 
1) Scorer Task:
This is a hard task which keeps track of Timer and score of the player. The time for the game is 50 sec. We initialize the counter to 100 and then each time we reduce the counter and when timer is zero we exit. Currently we user update rate of 500000 microsecond and WET as 5000000 microsecond.(According to shark manual the WET will be ignored)
 
2) MovePlayerUp and MovePlayerDown Tasks:
These are the soft tasks Which are created at beginning but they are not activated. These tasks are activated when user presses up or down key. These tasks move change the Y co-ordinates of a player during each cycle and redraws player till the player reaches next leaf level. When Player reaches the next level this task is blocked using task_disable. For this tasks we have default period of 25000 microsecond, WCET 500 microsecond and MET 100.
 
 
3) Enemy Task:
This is soft task which is created during initialization. It Moves Enemy by 10 pixels during each execution cycle and checks if enemy touches the player co ordinates if it touches then we exit. For this tasks we have default period of 50000 microsecond, WCET 500 microsecond and MET 100.
 
4) Leaves Task:
These are soft tasks which are created during Initialization. Each task is responsible for moving a single leaf in water. It also check if player is on leaf if it is then it also changes the co ordinates of player and redraws it.
For this tasks we have default period of 50000 microsecond, WCET 5000 microsecond and MET 1000.
 
5) Others:
Apart from this we handle left or right move of player in Keyboard event. This is System Task and by default its soft TASK.
 
Synchronization:
 
We use following mutexs for synchronization:
 
We use Mutexs when accessing the co ordinates of players, leaves and Graphics card. Various tasks use those mutexs. Some tasks need to access various mutexs at same time. So in order to avoid cyclic wait we made some rules as we assign levels to each mutex. and when acquiring any high level mutex we must first release the lower level mutexs first. And after acquiring higher mutex we can take lower mutexs again.
 
1) grx_mutex: This mutex is used before doing any graphical output function. This mutex is highest level. Before taking this mutes we must release any leaves and player mutex if any.
 
2) player_mutex: This mutex is used before accessing any player co ordinates. This is second level of mutex. Before Acquiring this mutex we must release any leaves mutex if acquired.
 
3) Leaves_mutex: These mutexs are used before accessing any co ordinates of any leaf. This is lowest level of mutexs.
