What defines a 'modern processor'. The term is pretty slippery. The Crusoe used microcode to emulate x86 and could therefore emulate any processor architecture Transmeta wanted.
Crusoe was a pioneer in the low power market, the processor dynamically clocked itself in very small steps depending on need. This is a familiar feature now but was pretty revolutionary for the time. Interestingly, Linux Torvalds was in on the design and was on the board of Transmeta. A fair number were sold to Sony for their VIAO series of notebooks. Does Crusoe qualify as a 'modern' processor? In my book yes, but I have a very old book.. :0 best, Jeff
