I'm not sure what a "linear pre-fetch desirability" is, and I apologise
if someone has already mentioned the following (we lost a lot of news a couple
of weeks ago). The MU5 system developed at Manchester U had a "jump history
table" that tried to predict branches using an associative memory in a way
much like that used for page tables.  The MU5 system was described in the 25th
anniversary issue of CACM (sorry I can't remember which year, but it was the
Jan issue).
