HI Eric,
No. The 68040 (all variants including the LC and EC)
require a double-speed
clock input, but the internal pipeline does NOT execute at the double
speed. A 68040 with 33 and 66 MHz clock inputs actually runs at 33 MHz.
Motorola documentation is very clear on this. As soon as Motorola
atarted sending out "advanced information" data sheets it became apparent
that this would cause a lot of confusion.
Hmm, what an interesting surprise. I've read information that supports my
statements in several different places on the net. If this is a 'myth to be
killed' you've got some work ahead of you...
Confusion is right! Thanks for the clarification.
