CPU frequency must be 18MHz/9 = 2MHz. - - Memory timing uses a 8-phase clock, derived from a 20MHz(?) video clock (called VCLK0 here: - in the schematics, it comes from pin 6 of V8, and it is labelled "0'" in the video clock bus). - This clock is divided by G7, G6 and D5 to generate the signals we call VCLK1-VCLK11. The memory - clock phases Phi0-Phi7 are generated in D7, whereas PHI'14 and PHI'15 are generated in D8. - - When the CPU accesses RAM, wait states are inserted until the RAM transfer is complete. - - CPU clock: 18MHz/9 = 2MHz - memory cycle time: 20MHz/8 = 2.5MHz - CPU memory access time: (min) approx. 9/20MHz = 450ns - (max) approx. 25/20MHz = 1250ns - pixel clock: 20MHz/4 = 5MHz - screen size: 256*256 - HBL: 64 pixel clock cycles - VBL: 64 lines - horizontal frequency: 5MHZ/(256+64) = 15.625kHz - vertical frequency: 15.625kHz/(256+64) = 48.83Hz - - |<--------VIDEO WINDOW--------->|<----------CPU WINDOW--------->|<-- - _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ - VCLK0 |_| |_| |_| |_| |_| |_| |_| |_| |_| |_| |_| |_| |_| |_| |_| |_| |_| |_| | - _ ___ ___ ___ ___ ___ ___ ___ ___ ___ - VCLK1 |___| |___| |___| |___| |___| |___| |___| |___| |___| | - _ _______ _______ _______ _______ - VCLK2 |_______| |_______| |_______| |_______| |______| - _ _______________ _______________ - VCLK3 |_______________| |_______________| |_______ - _ _______________________________ - VCLK4 |_______________________________| |_______ - - _ _ _ - PHI0 _| |_____________________________| |_____________________________| |_____ - _ _ _ - PHI1 _____| |_____________________________| |_____________________________| |_ - _ _ - PHI2 _________| |_____________________________| |_____________________________ - _ _ - PHI3 _____________| |_____________________________| |_________________________ - _ _ - PHI4 _________________| |_____________________________| |_____________________ - _ _ - PHI5 _____________________| |_____________________________| |_________________ - _ _ - PHI6 _________________________| |_____________________________| |_____________ - _ _ - PHI7 _____________________________| |_____________________________| |_________ - _ - PHI'14 _________________________________________________________| |_____________ - _ - PHI'15 _____________________________________________________________| |_________ - __________ __________________________________________________ - RAS* \___________/ \_a_________/ - ______________ __________________________________________ - CAS* \_______________/ \_a_____________/ - _________________________________________________________________________ - WR* \_b_________//////// - _________________________________________________________________________ - WRM* \\\\\\\\\\\\\\\\\\\\\\\\\\_b__________________________________/////////// - _________________________________________________________________________ - RDM* \\\\\\\\\\\\\\\\\\\\\\\\\\_c __________________________________/////////// - _________________________________________________________________________ - RA \\\\\\\\\\\\\\\\\\\\\\\\\\_a__________________________________/ - - DRAM - ADDRESS video row /\ video column /XXX\CPU row (a)/\ CPU column (a) /\ video row - - a: only if the CPU is requesting a RAM read/write - b: only if the CPU is requesting a RAM write - c: only if the CPU is requesting a RAM read - -*******************************************************************************/ - -#include "emu.h" -#include "includes/lviv.h" - -#include "cpu/i8085/i8085.h" - -#include "softlist.h" -#include "speaker.h" - -#include "formats/lviv_lvt.h" - - -/* I/O ports */ - -void lviv_state::io_map(address_map &map) -{ - map(0x00, 0xff).rw(FUNC(lviv_state::io_r), FUNC(lviv_state::io_w));
