Abstract
In an embodiment, an integrated circuit may include edge triggered flops that launch data to start a clock cycle and that capture data at the end of the clock cycle. Combinatorial logic circuitry may be coupled between the launching and capturing flops, and may be configured to operate on the launched data to generate result data for the capturing flops. One or more latches may be provided in the combinatorial logic circuitry, which may close and capture intermediate values responsive to an opposite edge of the clock than the edge that triggers the edge-triggered flops. In an embodiment, the clock to the latches may be gated with an enable. When the integrated circuit is not operating in the subthreshold voltage region, the enable may be in the disabled state. When operating in the subthreshold voltage region, the enable may be in the enabled state.
