gated clocks

Gating clocks is a tecnique "dangerous" but usefull in very low power Application Specific IC: for example it is used in Pacemaker Chips.

Re: gated clocks

In multi-million gates SoC designs, gated clock is almost mandatory. It custs down power significantly. Without clock gating, the chip will definitely melt.

Clock enable is basically a mux where one input is feedback. The flops in Xilinx devices already have this mux built in. It's natural to take advantage of it.
