fast print

The other day, 10.29.97, at 18:00, Kostya Bykov, wrote to All on regarding "fast print", looking at this disgrace, I decided to intervene in this conversation and this is what I wrote: Glad to welcome you, Kostya! KB> Maybe someone knows how to implement a fast one KB> print text to the screen. KB> It seems there is a special(?) font format and As for the font, it should not be like in the ROM, i.e. images characters should be stored not in a row at 8 bytes per character, but through 256. That is first the first byte of the first character, then the first byte of the second and so 256 bytes. Next is the second byte the first character, the second byte of the second character, etc. Simply put, in the art studio, right on the screen, you draw a font in the upper third of the screen (the first 8 vertical spaces), there Just 256 characters fit. Then you upload the screen file and you use only the first 8 sectors (2 kilobytes). this and There will be a font in a special format. When printing text, you do it differently than usual: LD HL, address on screen LD DE, symbol image -+----------- EIGHT TIMES --------- LD A,(DE) LD(HL),A INC H INC DE -+-------------------------------- otherwise: -+----------- EIGHT TIMES --------- LD A,(DE) LD(HL),A INC H INC D -+-------------------------------- Do not do cycles under any circumstances, DJNZ is about 100 extraclock cycles for each character. The font must be located at an address that is a multiple of 256. That is. youngest the address byte must be 0 (zero). The calculation of the symbol image in the font is done as follows: LD D,font address/256 (high byte of font address) LD E, code of the symbol to be displayed KB> analysis of strings(?), characters?

Glad I found you alive, Kostya!!! However, on 00 Oct 97 you wrote something addressed to All: KB> Maybe someone knows how to implement a fast one KB> print text on the screen. What text, in what format, how many characters is the line? KB> It seems there is a special(?) font format and KB> analysis of strings(?), characters? Would you like me to tell you the fastest output of a page of text at the moment? Write down: ld hl,data push hl What does the thread say? No!? Well, I’ll explain: the necessary bytes of the image of the text page There should be two bytes after the command code ld hl,nn. And so he signs map, accordingly it is necessary to repeat this piece for every two bytes image. It will turn out a lot, but believe me, this is the fastest conclusion at the moment any image (be it text or any other arbitrary picture).
