Well, Dave's approach is certainly no worse than the Intel ad which is
presented without several important OHBYTHEWAY's. Intel's assumtion that
all programs and data are <64k is no better than Motorola's assumtion
that they're all >64k. Realizing that this is a basic difference in
performance between the two processors, I'd like to see benchmarks that
address programs and data of sizes both <64k and >64k. (of course then
we can write benchmarks that use 12 registers to make the Motorola look
good, and ones that use 2 to make the Intel look good.)
