- I tried to measure the amount of free cycles I have after a chip-write
- (MOVE.L d0,(chip)+) on my computer , a A1200/30/28 Mhz.
- But not matter, which resolution an depth I took (different bandwidths)
- I got alwas 12 free cycles. Even in 8 planes shres, though the whole
- loop got dead slow.
- Is it possible, that after 16 cycles (MOVE.L d0,(a1) + 12 free cycles)
- the 68030 starts to wait for the write acess ?? If yes, why ?? That
- seems to be a strange manner to me, because the performerance could have
- been increased without that limitation.
