Method and apparatus for shifting the bits of a wide data word
Abstract:
In one embodiment, a method and apparatus for shifting the bits of a data word are disclosed. For example, a deserializer according to one embodiment includes an input register bank for capturing serial data comprising n bits, an intermediate register bank, and a strobe mux coupled to an input of the intermediate register bank. An input of the intermediate register bank is coupled to an output of the input register bank. The strobe mux comprises a single multiplexer configured to select a bitslip strobe signal that controls an order in which the n bits of the serial data are captured in the intermediate register bank.
