Partially Fixed Point Multiplication

Majid Khabbazian, T. Aaron Gulliver and Vijay K. Bhargava

Abstract: A new technique is proposed in which bandwidth and memory are together used to reduce both the number of point additions and doublings required in computing random point multiplication. Using the proposed technique, we show that a significant speed-up can be obtained at the cost of slightly increased bandwidth. In addition, we show that the proposed technique is well-suited for parallel processing.
