A funnel shifter is just a big, stinking mux with 2n inputs and n outputs.
Two words are concatenated (i.e. butted up to each other, no this isn't 
some violation of the recent supreme court ruling) and a single word is
chosen for the output starting at some given bit position of the two-word
input.  Thus, it is easy to effect a barrel shifter by simply supplying
the same data in both of the input words.  No, there are NOT two shifters
on the Am29332, just the one funnel shifter.  Another application of the
funnel shifter is to extract an unaligned data word from two adjacent,
aligned data words.

If this isn't sufficiently clear, I can have the 29332 data sheet sent
to you....

Is an Oxidized Instruction Set Computer the opposite of a Reduced
