Abstract
Efficient parallel processing of algorithms involving Galois Field arithmetic use data slicing techniques to execute arithmetic operations on a computing hardware having SIMD (single-instruction, multiple-data) architectures. A W-bit wide word computer capable of operating on one or more sets of k-bit operands executes Galois Field arithmetic by mapping arithmetic operations of Galois Field GF(2 ) to corresponding operations in subfields lower order (m<n), which one selected on the basis of an appropriate cost function. These corresponding operations are able to be simultaneously executed on the W-bit wide computer such that the results of the arithmetic operations in Galois Field GF(2 ) are obtained in k/W as many cycles of the W-bit computer compared with execution of the corresponding operations on a k-bit computer.
