- Yep, $dffxxx registers are slow, that`s true. But I`m refering to machines I know:
-
- - A1200 with 68030/50Mhz with overdrive CDROM.
-
- - CD32 expanded with keyboard and 68030/50Mhz.
-
- (On sysinfo both machines show equal speed values.)
-
- I tried many C2P-codes, but noone could beat the 3.1 OSfunktion on the CD32.
-
- In my opinion this results by the high number of cache misses you get with C2P by CPU.
- Most values are read once, thus not cacheable. Instructioncache is very effective
- with most of the C2Pcodes, but it doesn`t give such a boost that you could reach
- akikos registers.
