Efficient spline interpolation

The problem of interpolating data points using a smooth function has many existing solutions. In particular, the use of piecewise polynomials (splines) has provided solutions with user controlled smoothness. In this paper we introduce a new interpolation procedure which utilizes multiple knot Hermitian splines. The technique renders the interpolating spline function using fixed point shifts and additions. In applications requiring parallel computation the use of these simpler operations implies a significant reduction in hardware complexity.
