WRL Technical Report TN-9 is available.  (It actually has been available for
some time, but we don't have any kind of formal announcement mailing list in
place.)  The title and abstract:

Smart Code, Stupid Memory: A Fast X Server for a Dumb Color Frame Buffer

Processor speeds are improving faster than memory access speeds.  The
current generation of RISC processors can perform many 2-dimensional
graphics operations at memory bandwidth speeds, rendering specialized
hardware unnecessary.  This paper describes the DECStation 3100 color
frame buffer hardware and several of the graphics algorithms used in
the X server implementation.  Measured performance numbers are
presented and compared to memory bandwidth speed, and possible frame
buffer improvements are discussed.
