摘要: This paper introduces a modification to an index calculus representation for the double-base number system (DBNS). The DBNS uses bases 2 and 3; it is redundant (very sparse) has simple two-dimensional representation. An extremely sparse form of single non-zero digit represent any real with arbitrary precision. In this case can be identified by its coordinates (indices) in space. proposed paper, targeted DSP inner product computations, coefficient vector 2-digit data vector. We show that reduction over 80% hardware cost possible using hybrid compared original single-digit technique.
