; **************************************************************************** ; Q-TRIS ; ; Tetris clone and the first game ever developed for QNICE-FPGA. ; ; The rules of the game are very close to the "official" Tetris rules as ; they can be found e.g. on http://tetris.wikia.com/wiki/Tetris_Guideline ; ; Clearing a larger amount of lines at once (e.g. Double, Triple, Q-TRIS) ; leads to much higher scores. The scoring algorithm is: ; (<amount of cleared lines> ^ 2) x <Level> ; ; Clearing a certain treshold of lines leads to the next level. The game ; speed increases from level top level. If you clear 1.000 lines, then ; you win the game. ; ; The game uses the PS2/USB keyboard and VGA, no matter how STDIN/STDOUT ; are routed. All speed calculations are based on a 50 MHz CPU that is equal ; to the CPU revision contained in release V1.3. ; ; The game can run stand-alone, i.e. instead of the Monitor as the "ROM" ; for the QNICE-FPGA - or - it can run regularly as an app. In the latter case ; it loads to 0x8000. #define QTRIS_STANDALONE for the standalone mode. ; ; done by sy2002 in January and February 2016 ; **************************************************************************** ; ; PERFORMANCE TEST VERSION TO DETERMINE THE MIPS DURING PLAYING Q-TRIS ; ; ISA 1.5: ; ; Measurement #1 done on MEGA65 by sy2002 on July, 13th 2020: ; Clock cycles: 0003 C771 F13E = 16.231.035.198 => 324,62 sec ; Instructions: 0000 EA6E 73D1 = 3.933.107.153 => 12,12 MIPS ; ; Measurement #2 done on Nexys 4 DDR by sy2002 on July, 14th 2020: ; Clock cycles: 0001 0078 BDA3 = 4.302.880.163 => 86,06 sec ; Instructions: 0000 3E2F CF3E = 1.043.320.638 => 12,12 MIPS ; ; ISA 1.6: ; ; Measurement #3 done on Nexys 4 DDR by sy2002 on August, 18th 2020: ; Clock cycles: 0005 33BE B478 = 22.342.972.536 => 446,86 sec => 7:27 min ; Instructions: 0001 5996 6BCC = 5.797.997.516 => 3,85 cycles / instruction ; => 12,97 MIPS ; ; **************************************************************************** #undef QTRIS_STANDALONE #include "../dist_kit/sysdef.asm" #include "../dist_kit/monitor.def" #ifdef QTRIS_STANDALONE .ORG 0x0000 ; start at 0x0000 AND 0x00FF, SR ; make sure we are at rbank 0 MOVE 0xFEFF, SP ; setup stack pointer #else .ORG 0x8000 ; start at 0x8000 #endif ; PERFORMANCE TEST CODE MOVE IO$CYC_STATE, R0 ; reset hw cycle counter MOVE 1, @R0 MOVE IO$INS_STATE, R0 ; reset hw instruction counter MOVE 1, @R0 ; STANDARD Q-TRIS CODE RSUB INIT_SCREENHW, 1 ; clear screen, no hw cursor RSUB INIT_GLOBALS, 1 ; init global variables RSUB PAINT_PLAYFIELD, 1 ; paint playfield & logo RSUB PAINT_STATS, 1 ; paint score, level, etc. RSUB HANDLE_PAUSE, 1 ; check space, inc pseudo rnd NEXT_GAME RSUB DRAW_FROM_BAG, 1 ; randomizer algorithm MOVE R8, R3 ; R3: result = next Tetromino ; use "draw from bag" algorithm to dice a new Tetromino MAIN_LOOP RSUB DRAW_FROM_BAG, 1 ; dice another Tetromino MOVE R3, R4 ; R4: old "next" = new current MOVE R8, R3 ; R3: dice result = new "next" RSUB PAINT_NEXT_TTR, 1 ; fill the preview window MOVE RenderedNumber, R0 ; make sure the renderer...
