No new C processors have entered the market in that time either. With rather few exceptions (anyone remember Sun's special Java chips? Looks like they did really well then), people don't design processors for specific languages any more at all. --tim

With the exception C processors never existed.

Unless we agree that C is machine language in disguise. kt -- http://thelaughingstockatpngs.com/ http://www.facebook.com/pages/The-Laughingstock/115923141782?ref=nf

New processors appear all the time, just none that knows about Lisp (data structures, dispatching, function calling, tags, GC, ...), like the chips from Symbolics and TI did. Many processors are very much tied to some language (variants of C and Java) and you need to use the language provided to exploit the hardware (like the languages that one now uses to program GPUs.). Language support is in some chips. ARM chips have for example have 'Gazelle': http://www.arm.com/products/multimedia/java/jazelle.html 'Gazelle technology is a combined hardware and software solution from ARM. ARM Jazelle technology software is a full featured multi-tasking Java Virtual Machine (JVM), highly optimized to take advantage of Jazelle technology architecture extensions available in many ARM processor cores. ARM Jazelle technology hardware extensions are available from over 50 ARM silicon partners. ARM Jazelle technology software is available pre-integrated into a complete Java platform from a range of ARM software partners or directly from ARM.' See the papers on the right side of that page for some background.

There were processors produced by AT&T / Bell Labs in the 80s and early 90s which were heavily oriented to C. I think these were the CRISP and Hobbit (which may have been the same, I'm not sure. But my point was that people don't optimise processors to for a particular HLL any more (or for ease of programming in assembler). |
