You have n hardware gates making simple operations each with proper latches as needed, all latches use the same clock signal. One data is encoded in L cycles, but a new data set is started in every one cycle.

So yes - processing of one dataset takes L cycles, but processing for example 1G datasets takes 1G +L-1 cycles.
