Hacking on Wikipedia requires a strong stomach.  Exerpted from "If?" by [[Rudyard Kipling]]:

:If you can bear to hear the truth you've spoken
:Twisted by knaves to make a trap for fools,
:Or watch the things you gave your life to, broken,
:And stoop and build'em up with worn-out tools

...then maybe you've got what it takes to write stuff here, and make it stick.

Here's my plan:

*Microarchitecture
**[[Classic RISC Pipeline]]
**[[Cache]]
***[[CPU caches]] -- this wasn't strictly necessary, and got huge.  Still to do: cache hierarchy and the similarity to predictors.
***[[Loop nest optimization]] -- just an example so far.
***[[Memory coherence|Multiprocessor cache coherence]] -- haven't touched it yet
**Out-of-order execution
**[[Register renaming]] -- covers OoO to some extent
**Virtual to physical address translation
***TLBs
*Physical implementation
**Logic circuit families
***CMOS
****stack-latch flops
****pulse flops
****flops versus latches
****stall signals
***Domino
****implicit latches
**[[Phase-locked loop]]s -- total mess!
**CPU recurences
***[[branch predictor]]
***in-order dispatch
***out-of-order issue
***ALU-bypass
****skewed datapath
****conditional moves
***integer load
****[[Sum addressed decoder]]
***Floating-point unit
****Multiplication, including Booth recoding, modified Booth-2 and -3

Complete rewrites or new pages:
* [[Load-balanced switch]]
* [[hydrogen economy]] -- d'oh! just when LeonardG and I had this looking reasonable, another couple of editors made it worse!
* [[rocket fuel]]

Major hacking:
* [[wind turbine]] (still needs a '''lot''' of help).
