Hey, i'm back, 320X200 MODE STUFF?, use them with care! :)

i never use stosb cause the u and v pipelines can exetute "mov [es:edi],al"
and "inc edi " on the same clock
if [es:edi] is a graphic buffer in cache then the sequence use only 1 cycle

i have writen stosb to make the shortest possible in term of instructions

so now:

Code:

putpxl:
  mov edi,[x.resolution]
  imul edi,[y]
  add edi,[x]
  mov [es:edi],al
  ret

Code:

putpxls:
  mov edi,[x.resolution]
  imul edi,[y]
  add edi,[x]
  mov ecx,[count]
@@:
  inc edi
  xor [delta],320  
; xor [delta],edi!
  mov [es:edi],al
  add edi,[delta]
;the best is to integrate putpxl inside the function
;the init pxl is in the init of function
;and the loop of function will access screen
;with only one instruction 
;the delta is a conbinaison of X and Y delta
;delta is a 2D vector!!!
;so you can move pxl as you want
;and with a delta string, it can make some maths functions
;a vertical line is vector delta=320 or -320
;an horizontal line is delta=1 or -1
; etc etc...
  loop @b
  ret

the best is to never use putpixel
