Luckily for UK the ARM.ltd tradition continued on, but personally I would not point to the RISC aspect as much as to those symmetric 16-32 registers usually designed into RISC designs, making it possible to run fast internally with slower memory. (someting Intel also does, in their own CISC, sillycone wasting way, counting on fast, power wasting RAM or hard to handle caching stuff) The 386 architecture has always used the CPU external memory as a "fast" replacement for local variables, works OK if lots of power and cooling hardware available, but totally outdated these times. (x86 architectures only have 3-4 usable registers, lots of back-and-forth-writing-loading from memory) Skipping these fundamental bad issues of the CISC x86 architecture, ARM.ltd has additionally adopted some really smart ideas, like mixing 16 and 32 bit code when either one is the smartest thing to use. The tradegy for Intel is probably that they locked themselves into non-RISC architectures when the AMD 12MHz 286 beat them, when RISC became a non-Intel word. (plus the anti-DSP thing against Intel in the early 90s) However, the joke has been that any Pentium actually is designed with something between 16 to 128 RISCs in it, but Intel cannot say that is the case. ARM was and is "great", but their compilator is lousy. Ilmarinen Anyway, it has been "fun" to watch how "everyone" has adopted, bought an ARM license during the last 3-5 years. Most contracts probably demanding that no big fuzz should be made about that little fact?? (on the other hand, similar designs float around, the Hitachi SH-family, etc, most of them going back to when AMI sold everything it had) But at that point the OS becomes important, the ARM-SYMBIAN axis (unluckily kind of banned by any media or capital connected to Intel-MSFT, most funnny the (MS)CNBC-UK) But, no processor is better than its compiler and tools, what the Intel-MSFT axis have improved on since they got rid of Watcom. My personal guess is that those times are gone, even Intel does not need to obey MSFT anymore...
