In these areas cpu can access ram since scanlines are out of -- visible display. In progessive mode there are video access around lines 240. -- These accesses will create video artfacts aound mid display. In VHDL code -- ram access is muliplexed between cpu and scanlines by using hcnt(0) in -- order to avoid these artefacts. -- -- Sprite data are stored first by cpu into a 'cache' buffer (staging ram at -- K6/L6) this buffer is read and write for cpu. After visible display, cache -- buffer (512x8) is moved to actual sprite ram buffer (512x8). Actual sprite -- buffer is access by transfer address counter during 2 scanlines after -- visible area and only by sprite machine during visible area. -- -- Thus cpu can read and update sprites position during entire frame except -- during 2 lines. -- -- Sprite data are organised (as seen by cpu F000-F1FF) into 128 * 4bytes. -- bytes #1 : Vertical position -- bytes #2 : code and attribute -- bytes #3 : Horizontal position -- bytes #4 : not used -- -- Athough 1x1 pixel defintion sprite position horizontal/vertical is made on -- on a 2x2 grid (due to only 8bits for position data) -- -- Z80-CTC : interruption ar managed by CTC chip. ONly channel 3 is trigered -- by hardware signal line 493. channel 0 to 2 are in timer mode. Schematic -- show zc/to of channel 0 connected to clk/trg of channel 1. This seems to be -- unsued for that (Kick) game. -- -- Z80-CTC VHDL port keep separated interrupt controler and each counter so -- one can use them on its own. Priority daisy-chain is not done (not used in -- that game). clock polarity selection is not done since it has no meaning -- with digital clock/enable (e.g cpu_ena signal) method. -- -- Ressource : input clock 40MHz is chosen to allow easy making of 20MHz for -- pixel clock and 8MHz signal for amplitude modulation circuit of ssio board -- -- TODO : -- Working ram could be initialized to set initial difficulty level and -- initial bases (live) number. Otherwise one can set it up by using service -- menu at each power up. -- +----------------------------------------------------------------------------------+ ; Fitter Summary ; +------------------------------------+---------------------------------------------+ ; Fitter Status ; Successful - Wed Nov 13 19:50:34 2019 ; ; Quartus Prime Version ; 18.1.0 Build 625 09/12/2018 SJ Lite Edition ; ; Revision Name ; satans_hollow_de10_lite ; ; Top-level Entity Name ; satans_hollow_de10_lite ; ; Family ; MAX 10 ; ; Device ; 10M50DAF484C6GES ; ; Timing Models ; Preliminary ; ; Total logic elements ; 6,545 / 49,760 ( 13 % ) ; ; Total combinational functions ; 6,307 / 49,760 ( 13 % ) ; ; Dedicated logic registers ; 1,671 / 49,760 ( 3 % ) ; ; Total registers ; 1671 ; ; Total pins ; 105 / 360 ( 29 % ) ; ; Total virtual pins ; 0 ; ; Total memory bits ; 938,560 / 1,677,312 ( 56 % ) ; ; Embedded Multiplier 9-bit elements ; 0 / 288 ( 0 % ) ; ; Total PLLs ; 1 / 4 ( 25 % ) ; ; UFM blocks ; 0 / 1 ( 0 % ) ; ; ADC blocks ; 0 / 2 ( 0 % ) ; +------------------------------------+---------------------------------------------+ --------------- VHDL File list --------------- de10_lite/max10_pll_40M.vhd Pll 40MHz from 50MHz altera mf rtl_dar/satans_hollow_de10_lite.vhd Top level for de10_lite board rtl_dar/satans_hollow.vhd Main CPU and video boards logic rtl_dar/satans_hollow_sound_board.vhd Main sound board logic rtl_dar/ctc_controler.vhd Z80-CTC controler rtl_dar/ctc_counter.vhd Z80-CTC counter rtl_mikej/YM2149_linmix.vhd Copyright (c) MikeJ - Jan 2005 rtl_T80_304/T80se.vhdT80 Copyright (c) 2001-2002 Daniel Wallner (jesus@opencores.org) rtl_T80_304/T80_Reg.vhd rtl_T80_304/T80_Pack.vhd rtl_T80_304/T80_MCode.vhd rtl_T80_304/T80_ALU.vhd rtl_T80_304/T80.vhd rtl_dar/kbd_joystick.vhd Keyboard key to player/coin input rtl_dar/io_ps2_keyboard.vhd Copyright 2005-2008 by Peter Wendrich (pwsoft@syntiac.com) rtl_dar/gen_ram.vhd Generic RAM (Peter Wendrich + DAR Modification) rtl_dar/decodeur_7_seg.vhd 7 segments display decoder rtl_dar/proms/satans_hollow_cpu.vhd CPU board PROMS rtl_dar/proms/satans_hollow_bg_bits_2.vhd rtl_dar/proms/satans_hollow_bg_bits_1.vhd rtl_dar/proms/satans_hollow_sp_bits.vhd Video board PROMS rtl_dar/proms/satans_hollow_sound_cpu.vhd Sound board PROMS rtl_dar/proms/midssio_82s123.vhd ---------------------- Quartus project files ---------------------- de10_lite/satans_hollow_de10_lite.sdc Timequest constraints file de10_lite/satans_hollow_de10_lite.qsf de10_lite settings (files,pins...) de10_lite/satans_hollow_de10_lite.qpf de10_lite project ----------------------------- Required ROMs (Not included) ----------------------------- You need the following 16 ROMs binary files from satans_hollow.zip and midssio.zip(MAME) sh-pro.00 CRC 95e2b800 sh-pro.01 CRC b99f6ff8 sh-pro.02 CRC 1202c7b2 sh-pro.03 CRC 0a64afb9 sh-pro.04 CRC 22fa9175 sh-pro.05 CRC 1716e2bb sh-snd.01 CRC 55a297cc sh-snd.02 CRC 46fc31f6 sh-snd.03 CRC b1f4a6a8 sh-bg.00 CRC 3e2b333c sh-bg.01 CRC d1d70cc4 sh-fg.00 CRC 33f4554e sh-fg.01 CRC ba1a38b4 sh-fg.02 CRC 6b57f6da sh-fg.03 CRC 37ea9d07 midssio_82s123.12d CRC e1281ee9 ------ Tools ------ You need to build vhdl files from the binary file : - Unzip the roms file in the tools/satans_hollow_unzip directory - Double click (execute) the script tools/make_satans_hollow_proms.bat to get the following 6 files satans_hollow_cpu.vhd satans_hollow_sound_cpu.vhd satans_hollow_bg_bits_1.vhd satans_hollow_bg_bits_2.vhd satans_hollow_sp_bits.vhd make_vhdl_prom midssio_82s123.12d midssio_82s123.vhd *DO NOT REDISTRIBUTE THESE FILES* VHDL files are needed to compile and include roms into the project The script make_satans_hollow_proms.bat uses make_vhdl_prom executables delivered both in linux and windows version.
