Configurable storage elements

摘要

A low power sub-cycle reconfigurable conduit is provided. The low power reconfigurable conduit is a clocked storage element that consumes less power when performing low-throughput operations that do not require sub-cycle rate. The low power conduit includes a first configurable routing multiplexer that is reconfigurable to select one of several inputs at a first clock rate. The low power conduit also includes an array of storage elements for storing output data from the configurable routing multiplexer at the first clock rate. Each storage element in the array of storage elements operate at a second clock rate that is slower than the first clock rate. Each storage element receives a different phase of a clock that operates at the second clock rate. The low power conduit also includes a second configurable routing multiplexer that is reconfigurable to select from the array of storage elements at the first clock rate.
