'Scuse me?
Mflops per MHz
= Mflops / MHz
Millions Flop / Sec
= --------------------
Millions Hertz / Sec
= Floating Point OP / Hertz
= FLOP per Cycle.
In other words, how many (or few) floating point operations happen in a
single cycle. Yeah, it's gonna be small number, but not as silly a number
as your derivation shows.
