030 dcache pre-fetch
Posted by: earx Apr,20.2005-14:15 

i was wondering if anyone knows how much cycles the instruction:

move.w (a0),dn

will stall when there's a data cache miss on 68030? i reckon the 030 tries to pre-fetch a complete long into dcache, so 2 words are read from the st ram, while it should only be 1? does this mean there is a 4 cycle stall?
