Sequential logic is the form of Boolean logic where the output is a function of both present inputs and past outputs. In most cases, the output signal is fed back into the circuit as a new input. Sequential logi

Sequential clock gating provides significant power savings because it not only switches off the clock going to registers but also the datapath logic in the fanout of gated registers. However, RTL synthesis tools are not capable of identifying sequential clock gating opportunities. Fortunately, recently ...

. The floating point divider is one of the most complicated logic blocks in arithmetic intensive digital designs. This paper discusses the different types of dividers with an emphasis on floating point sequential dividers. Performance comparisons (area and delay) of combinational and sequential dividers...
