I keep hearing it, and the two processors have nothing in common except maybe some vague fuzzy "if you liked the 6502, you'll probably find the ARM to your taste". The ARM is a classic RISC processor with a couple of twists - the barrel shifter in the data path before the ALU, and the four bit condition code on each instruction (all instructions are conditional). All operations are register-register. The only instructions that touch memory are load and store. This is clearly quite different to the 6502, in which almost all instructions touch memory, and you don't have any register-register operations.
