.... requirements of the general algorithm, not all of the underlying verifications with respect to the general algorithm) Once a general algorithm and instantiation is selected (and verified if not already provided) the mapping to hardware is performed using the Derivational Reasoning System (DRS) [4], to transform the algorithm to efficient hardware. This process is demonstrated in this paper for subtractive division algorithms. 1 The work in this paper is abstracted such that all work is done based on reals and integers as done in [8] not bits and bit vectors, making the reasoning process ....
....included with PVS are libraries providing support for bit vectors and finite sets. In PVS, the real numbers are a base type, and other numeric types are defined as subtypes of the reals. This allows specifications to freely mix operations on numeric types. 3. 3 A Brief Introduction to DRS DRS [4] mechanizes an algebraic framework for digital hardware design. It is a transformational system that emphasizes a correct by construction approach. The design proceeds through a series of behavior preserving transformations. DRS provides three levels of representation for the evolving design. At ....
