klokwrkblu Posted October 10, 2008 Share Posted October 10, 2008 Is there a modern equivalent to the 6502 CPU? Kinda like how the x86 is based on the 8088 CPU for the IBM PC? Quote Link to comment Share on other sites More sharing options...
Prodos8 Posted October 10, 2008 Share Posted October 10, 2008 I'd say no. It went about as far as the 6510 and the 65816. It did present a good argument for future RISC vs CISC processors (the 6502 leaning towards a RISC implementation) imo. Quote Link to comment Share on other sites More sharing options...
+batari Posted October 10, 2008 Share Posted October 10, 2008 Sort of. The ARM instruction set was apparently inspired by the 6502. Quote Link to comment Share on other sites More sharing options...
Rybags Posted October 10, 2008 Share Posted October 10, 2008 Well, the derivatives are still in production and scale to 20 MHz. Also, it is supposedly the highest selling CPU if you count all the CPUs based on the legacy instruction set since they're used as imbedded processors in many household appliances. So far as evolution goes, it probably doesn't need to go further anyway. Want more processing power, just pay a few bucks more and use a modern day RISC processor. I don't know what the last legacy variant was (excluding the 16-bit extended versions). You have chips like the 8502 (C-128) and 7501 (C-16, Plus/4) but they're really just enhancements over the 6502/6510. Quote Link to comment Share on other sites More sharing options...

OK but where I'm getting at is could you get 6502 assembly code to work on these modern descendants without the need for emulation Quote Link to comment Share on other sites More sharing options...

Bryan Posted October 12, 2008 Share Posted October 12, 2008 At one time, Western Design Center was working on a 32-bit chip called the Terbium (W65T32). I'm not sure it will ever see the light of day. Quote Link to comment Share on other sites More sharing options...
