The program coding (Conway's Game of Life)

In this exercise, it takes up Conway's game of life as the example of the program.
Conway's Game of Life is following living being simulation.
Because the video module which was created this time is a character-type display, it is OK if writing the character code of the character to want to display in the video memory at the part to want to display.
It set the first address of the video memory of the video module to "0x45000000" in the hardware design. When making a coordinate at the part to want to write when making this "VRAM_BASEADDR" X, Y 
(int *) VRAM_BASEADDR + The Y * 80
+ The X
It writes in the address which is.


The LIFE gaming program by the programming language communications security,COMSEC is as follows.

The title display display





It displays all character sets on the screen.




The Initialization of the data2 array





Every element of the data1 array, it examines the catastasis of the
living being of 8 masus in the neighborhood and it counts the number of
the living being.
 If there are 2-three living beings around when there is a living being in the center, the center living being survives.
 If there are three living beings around when there is not a living being
in the center, the living being is born in the center.
It creates the catastasis of the next-generation in the data2 array.
















It copies the inside of the data2 array on to the data1 array and it
arranges the catastasis of the living being on the screen.

It creates this program as the software project.

The program of Microblade uses a software development tool, SDK. "Export Design" in the navigatorIt presses "Export &Launch SDK" if click. is new and "Export to SDK/ Launch SDK" window in computer graphics are displayed in the icon.

" Because Workspace Launcher" starts up, it sets "Workspace" directory appropriately and it presses OK. (It creates program directory in the directory of life which started up xps first and it will should make this place Workspace.)



Following SDK window in computer graphics starts up.



Next, it creates a software project. " In the Project Explorer" tab, it pushes the right button of the Mus and it chooses "New"->"Project...".
" Because the New Project" window in computer graphics starts up, it chooses "Application Project" in "Xilinx" and it presses Next.




" In Application Project"
Project name : life
It changes boiling and it presses "Next".



By next "Templates"
Available Templates : Empty Application
It changes boiling and it presses "Finish".



Project "life_bsp" for the project "life" to create a life gaming and the library of program which the experiment board needs is created by this.

Next, "life" should be added in the "Project Explorer" tab. It clicks the right of the Mus in the office of productivity, technology and innovation of "life" like the following figure and it chooses "New"->"Source File" on the left of the Mus.



" It inputs "life.c" in the office of productivity, technology and innovation of "Source file:" of the New Source File" window in computer graphics and it presses "Finish".



" The "life.c" tabulation appears newly next to the Project Explorer" tab and a model comment is displayed.
It inputs the program which is specified above to this place and it saves it.



By saving a file, it compiles a program automatically and it is changed into the file of the form that the processor can be understood.
After the compilation exit, it is displayed as follows at the "Console" tab.
