6502 or ARM core selection?

[Arlet]

I remember reading somewhere that the big ARM device has code protection enabled, and that it can't be programmed anymore.

Samuel found a table showing the 6502 (actually the 6510, but that's the same thing) as having 32 or 36 Dhrystone score at 1 MHz (and therefore about 0.02 DMIPS/MHz)
...
Edit: added conversion between Dhrystone score and DMIPS

ARM7 is a 3-stage pipeline IIRC. It should do about 0.7 DMIPS/Mhz IIRC.
You need about 1 IPC to hit 1.5 DMIPS/Mhz, so an ARM7 is doing about 0.5 IPC, or stated otherwise, about 2 clocks per instruction.
