Hi,
I have a loop that needs to clear a 4096 byte area.
I would like it to be as fast as possible, but this is
not critical.
Here's what I came up with:
; need to clear data area
; data area is 4096 bytes
; 4096 = (255*16)+16
ld hl,DATA_AREA
ld c,16
@@start_loop1:
ld b,255
@@clear_byte:
ld (hl),0
inc hl
djnz @@clear_byte
dec c
jp nz,@@start_loop1
ld b,16
@@start_loop2:
ld (hl),0
inc hl
djnz @@start_loop2
It appears to work OK, but surely there must be a
simpler way or a faster way?
Any suggestions? Does anyone know of any good docs on Z80 code
optimisation?
Thanks,
Tony
