1. A transform processor system comprising:

  • an input circuit generating a driving function signal;

    a memory storing a plurality of input points, each input point having a plurality of parameters;

    a coefficient processor generating transform coefficients in response to the driving function signal;

    a first transform processor coupled to the coefficient processor and to the memory and generating a first transformed point in response to a first one of the plurality of input points stored by the memory and in response to the transform coefficients;

    a second transform processor coupled to the coefficient processor and to the memory and generating a second transformed point in response to a second one of the plurality of input points stored by the memory and in response to the same transform coefficients as used for the generation of the first transform point; and

    an output circuit coupled to the first transform processor and to the second transform processor and generating transformed output signals in response to the first transformed point and the second transformed point.
