Since with 40+ cycles on most bytes I can't do it on the fly, I need to read/decode off-the buffer. That would add cycles and put me in the range of 200+ cycles, which is about the same as what 1571 routines do off the buffer. > > Ah OK, I thought you meant 40 cycles for the whole 5 bytes, which is > obviously impossible :-) With 186 cycles for a 5 byte buffer, that means > 37 cycles per byte, which should not be that hard? Let me think it over > the next days ;-) Gladly :-) Anything that can be faster than that is a winner here! I still have to analyse the nitrox loader, for which I obtained sources recently. It was the fastest pure software loader using standard CBM format. -- SD! Message was sent through the cbm-hackers mailing listReceived on 2013-01-15 15:00:40
