Hmm... So, why was the Sega Genesis billed as a 16-bit machine? It uses a
68k.
If memory serves, because it has a 16-bit graphics pipeline.
Peace... Sridhar
So
what's your thoughts on the 8088? 16-bit registers, 8-bit data path
(but with 16-bit addressing). Is it a 16-bit CPU or an 8-bit CPU?
ALU and
internal data path are 16 bits. It's essentially an 8086
multiplexed down to an 8 bit external data bus. That makes it a 16
bit processor in my book, albeit a crippled one. For the same reason
a MC68008 is a 16 bit processor in the same way that the MC68000 is.
