Witajcie,

ZX Spectrum jest względnie prostą platformą sprzętową, ale jednym z elementów, który do dziś spędza sen z powiek adeptom sztuki programowania w assemblerze, jest organizacja pamięci ekranu. Kiedyś analizując kod jednej gier kolega natknął się na taką oto procedurę, którą roboczo nazywaliśmy INCHL:


--- Kod: ---INCHL INC H
        LD  A,H
        AND 7
        RET NZ
        LD  A,L
        ADD A,32
        LD  L,A
        RET C
        LD  A,H
        SUB 8
        LD  H,A
        RET

--- Koniec kodu ---

Procedura dla podanego w parze rejestrów HL adresu ekranu zwraca adres bajtu znajdującego się w linii poniżej .... nasze życie było od tego czasu dużo prostsze. Mam nadzieję, że też Wam się przyda :)

Tygrys:
Dzięki zapodzielenie się hintem! Dodam że procedura działa również dla banków pamięci dla 128k.

matofesi:
Pamiętam, że u nas procedura nazywała się z jakiegoś powodu NEXTHL ;)
Ma tylko jedną wadę - za uniwersalność płacimy szybkością. Nic nie przebije tablicy albo odpowiednio zoptymalizowanego kodu, ale jeśli potrzebujemy takiego uniwersalnego rozwiązania, które można po prostu wywołać z dowolnego miejsca nie przejmując się specjalnie czasem wykonania to procedurka jest bardzo przydatna :)

... żeby umieścić zacytowaną przeze mnie procedurę w kontekście dla początkujących, zamieszczam poniżej fragment kodu wyświetlającego kontrowersyjno-pojednawczy obrazek (do skompilowania pod PASMO).

Z uwagi na chęć wykorzystania komendy LDI do transferu danych, procedura INC_HL zmieniła się w INC_DE:


--- Kod: ---    org 32768

start:
    di
    ld  hl, img
    ld  de, 16384
    ld  bc, 192*32
loop:
    push de

    ; copy one image line
    rept 32
    ldi                    ; (HL) --byte--> (DE), HL++, DE++, BC--
    endm

    pop de
    call inc_de

    ld  a, b
    or  c
    jr  nz, loop

    ; loop forever at the end
stop:
    jp  stop

inc_de:
    inc d
    ld  a, d
    and 7
    ret nz
    ld  a, e
    add a,32
    ld  e, a
    ret c
    ld  a, d
    sub 8
    ld  d, a
    ret
