US Patent 7132854 Data path configurable for multiple clocking arrangements

A data path (200) can be configured to accommodate different clocking arrangements. In one mode, data values may be output at a single data rate: one data value every clock cycle. In another mode, data values may be output at a double data rate: two data values every clock cycle. A data path (200) can be compact circuit structure, needing only an additional mode multiplexer (206) and inverter over a conventional D-type master-slave flip-flop.
