Abstract :
A CORDIC based processor array which can be programmed by switch setting to compute the Discrete Hartley, Cosine or Sine Transforms or their inverses is described. Through a novel formulation of the transform computations in the CORDIC framework, N-point transforms are mapped on to a linear array of [N/2]+1 CORDIC processors with minimal control overhead to incorporate the programmability
