Hierarchical clock gating
Web1 de set. de 2007 · Simulation results on various types of clock-gating at different hierarchical levels on a serial peripheral interface (SPI) design show power savings of about 30% and 36% reduction on toggle rate can be seen with different complex clock- gating methods. Clock gating is an effective technique for minimizing dynamic power in … WebBenefits of Clock Gating: 1) Dynamic Power savings. 2) Eliminating multiplexers saves area. In earlier designs we used to use multiplexer for each register which consumes lot of area if we have to implement multiplexer for every register. 3) Easy to implement - no RTL code change is required. Clock gating is automatically inserted by the tool.
