Abstract: Systems, apparatuses, and methods for implementing stripe-based self-gating and change detect signal propagation for retiming pipelines are disclosed. A circuit includes one or more stripes, with each stripe including a plurality of stages of registers, with each stage only receiving input signals from the preceding stage. For a given stripe, the first stage of registers are self-gated to reduce power consumption by only clocking a group of registers when any of their input signals change. The self-gating signals of the first stage of registers are combined together to create a change detect signal which is passed through a register and provided to a second stage of registers as a clock-enable signal. Accordingly, the second stage registers are only clocked when the change detect signal indicates a change will be forwarded from the first stage. This reduces power consumption for the second stage without causing the area increase associated with self-gating circuitry.
