I think you're showing your experience with x86 programming. It is true that low level optimization on a 486 is different from a Pentium which is different from a Pentium II ...etc.
As far as I know, all the 68k chips used in Palm devices execute instructions in the same number of cycles. The differences in speed are a function of the clock rate and the memory configuration. If you really must have the highest speed display access, you can write custom code for each display hardware. Other than that, any optimization you do should apply equally to all platforms. With OS/5, this game really changes. Optimization will require writing native Arm code. And the various Arm processors (TI, Intel, & Motorola) execute instructions at different rates, even after adjusting for clock speed. -- For information on using the Palm Developer Forums, or to unsubscribe, please see http://www.palmos.com/dev/support/forums/
