VHDL İLE TAM GÖMÜLÜ BİR TETRİS OYUNU GERÇEKLEŞTİRMESİ

Öz

Bu çalışmada, bir FPGA geliştirme ve eğitim kiti üzerinde tam gömülü olarak çalışan bir Tetris oyun kodu gerçeklemesi yapılmıştır. Bunun için, FPGA kiti üzerinde bağımsız olarak çalışan, VHDL donanım tanımlama dilinde orijinal bir Tetris oyun kodu tasarlanmıştır. Bu tasarımın özgün yanı, şimdiye kadar bu konuda yapılmış birçok çalışmadan üstün olarak, tasarlanan kodun veri tutma işlemi için herhangi bir SRAM modülü kullanmamasıdır. Kodun yazımında karo-haritalamalı şema denilen, bir grup pikselin tamamını bir karo olarak tanımlayan bir haritalama kullanılmaktadır. Bu şema ile, ilgili karo içindeki piksellerin tamamı için 1-bit bilginin tutulması yeterli olduğundan kod tasarımı oldukça kolaylaşmakta ve aynı zamanda kodun hızlı çalışması sağlanmaktadır. Oyun kodu VHDL donanım tanımlama dilinde yazılmıştır. Sistem olarak Altera DE0 geliştirme ve eğitim kiti kullanılmıştır ancak yazılan kodda yalnız standart VHDL fonksiyonları kullanıldığından kod diğer FPGA kitleri üzerinde de çalışabilmektedir.

A FULLY EMBEDDED TETRIS GAME APPLICATION IN VHDL

Öz

In this paper, a Tetris game code which runs on an FPGA development and education board is synthesized. To this end, an original Tetris game code that works solely on the FPGA board is designed in VHDL hardware description language. The novelty of this design lies in the fact that the Tetris code does not use any SRAM modules for storage unlike other embedded Tetris implementations published to date. What is more, the code uses a tile-mapped scheme in which the code groups certain pixels as a tile. Thus, a 1-bit register is enough for the current value of all the pixels that fall in the tile which improves the speed of the code and simplifies the design procedure. The code is written using VHDL hardware description language. Though Altera DE0 development and education board is used for the implementation, thanks to the usage of only the standard VHDL functions, the code can run on any other FPGA boards.
