Abstract:
Apparatus for combining data received sequentially on two lines into sequential output on one line comprising:means for latching first data that was previously output; means for latching second data to be output; and logic circuitry that processes and combines the latched first data and the latched data to be output, such that the data to be output is formed on said output line, wherein said logic circuitry comprises an â€œexclusive orâ€  logic and a clock signal input, wherein said first data to be output is latched on the rising edge of the clock signal received and said second data to be output is latched on the falling edge of said clock signal received, wherein the output of said exclusive or logic produces two separate data values to be output per period of said clock signal, one data value produced upon receipt of each edge of said clock signal.
