I really hate to admit this, but I've fallen behind in hardware. Sigh.
I'm an engineer dammit, not a programmer! Enough tantrums...

This is all brought up by not knowing what a "funnel shifter" is, as
mentioned in _Electronics_ June 16 (and I also have to admit that I've
fallen behind in my reading): "...the new 168-pin 32-bit Am29332 ALU
performs more functions than TI's 8832. The 29332 has a funnel shifter,
a barrel shifter, and an encoder..."

From which I infer that a funnel shifter is not a new, improved barrel
shifter, or there would be no need to have them both. A misaligned move
unit, perhaps? WHAT IS A FUNNEL SHIFTER?

I'd appreciate any comments, email or posted, perhaps with references so 
that I can find out what the circuits look like.
