Abstract EN
This paper presents a novel approach to implementing multiplication of Galois Fields with 2N.
Elements of GF(2N) can be represented as polynomials of degree less than N over GF(2).
Operations are performed modulo an irreducible polynomial of degree n over GF(2).
Our approach splits a Galois Field multiply into two operations, polynomial-multiply and polynomial-remainder over GF(2).
We show how these two operations can be implemented using the same hardware.
Further, we show that in many cases several polynomial-multiply operations can be combined before needing to a polynomial-remainder.
The Sandblaster 2.0 is a SIMD architecture.
It has SIMD variants of the poly-multiply and poly-remainder instructions.
We use a Reed-Solomon encoder and decoder to demonstrate the performance of our approach.
Our new approach achieves speedup of 11.5x compared to the standard SIMD processor of 8x.
