Systematic derivation of VLSI arrays for digital DSP algorithms

The authors present an overview of synthesis methods for VLSI array processors. The synthesis was based on expressing the algorithm in terms of a set of recurrence equations which were mapped onto a set of processing elements connected in a systolic fashion. A method for the synthesis of multirate arrays is outlined. to show the synthesis procedure, the systematic derivation of the array structure for infinite impulse response (IIR) digital filters is presented. The authors illustrate how these transformations can be applied
