ok, that is not good for my plans...
Is there any thing in the the 8kB of RAM that is always the same (lookup
table etc.) or did you already think of that? I'm curios since the
ATmega168 got 16kB of Flash that is as fast as the RAM (I think the chip
is made so it limits its maximum speed to the slowest memory, flash. it
also has some EEPROM besides the SRAM).
Ps. ATmega spec:
Architecture: 8-bit RISC, no FPU.
