High-speed data register for laser range finders

Abstract From the Canadian patent

A high-speed data register (11) for storing a series of data values received at a high-speed clock rate (RCCK) and including a first set of pipelined latches (17 19, 21) and a second set of pipelined latches (23 25, 27). Control circuitry (29) loads the received data values alternately into said first set of latches (17 19, 21) and said second set of latches (23 25, 27) from an input or "last" register (13) which stores the last data value received by the data register (11). Data values thus enter the register (11) at the high-speed clock (RCCK) rate but are loaded into each of the first and second set of latches at one-half that rate.
