Floating point accumulator - feedback loops

Hello, I am attempting to design a single precision floating point accumulator. DSPB reports that a latency of at least 9 clocks is needed in the accumulation loop to allow for the floating po...

If you really have to run at system clock rate, then you will need parallel accumulators.

Is there any reason you are using floating rather than fixed point? fixed point accumulators can complete in a single clock cycle (as can fixed point multipliers). You get huge performance increases with fixed point over floating.
