Apparatus for emulating the operation of an LFSR having at least one of one or more inputs and one or more outputs, wherein the state of the LFSR can be described by a state vector having sections describing the input or inputs, if any, of the LFSR, the contents of the LFSR and the output or outputs, if any, of the LFSR, wherein the state vector can be multiplied by a time shift matrix to time shift the state specified by the vector and wherein the apparatus comprises means for multiplying a first instance of the state vector by the matrix to produce a second instance of the state vector that is time shifted relative to the first instance and wherein one or both of the input and output sections of the state vector are dimensioned to accommodate, respectively, inputs that arrive at different times during the time shift specified by the matrix and outputs that are produced at different times during the time shift. |
