Honored ContributorThe speed of the M9K and Embedded multiplier in Cyclone 3?
Hello, would you please point me to this information. From long time ago I recall that M9K is 5 ns r/w cycle, but can not find reference any more. The question rose because I use 112.5 MHz clock to o...

Honored ContributorHi Eugeny:
I would still take the specifications given in the datasheet with a grain of salt. That's the maximum speed of the Memory block/Multipliers themselves. But routing and other logic pipelining usually is the limiting factor. At 112.5 MHz you shouldn't have any issues. I have an FFT block with 18x18 multipliers running at 160 MHz in a Cyclone III design. Pete
