ガロア拡大体・積算/積算加算・積和演算装置

Title:

ガロア拡大体・積算/積算加算・積和演算装置

Document Type and Number:

Japanese Patent JP5266354

Kind Code:

B2

Abstract:

A Galois field multiply/multiply-add/multiply-accumulate system includes a multiplier circuit for multiplying two polynomials with coefficients over a Galois field to obtain their product; a Galois field linear transformer circuit responsive to the multiplier circuit for predicting the modulo remainder of the polynomial product for an irreducible polynomial; a storage circuit for supplying to the Galois field linear transformer circuit a set of coefficient for predicting the modulo remainder for a predetermined irreducible polynomial; and a Galois field adder circuit for adding the product of the multiplier circuit with a third polynomial with coefficients over a Galois field for performing the multiplication and add operations in a single cycle.
