Abstract
The objective of this paper is to develop an efficient method for testing of numerical
computations based on algebraic concepts such as transcendental degree of field
extensions.A class of polynomially checkable functions is introduced, and for computation of the
functions from this class a new method for error detection/error correction is proposed.
This class of functions is shown to be large. The proposed method can also be extended to
testing of computations of functions which are not polynomially checkable.The preliminary results show great potential of this approach. In particular the
proposed approach will lead to substantial reduction in hardware overhead required for
multiple error detection and correction, as compare to the check sum method and other
existing techniques.
