The present invention relates to a processor and, more particularly, a truly flexible and versatile Configurable Galois Field Processor for applications which require operations over GF(2<pq>). Embodiments of the present invention have a unique configuration structure allows them to operate in either Single Instruction Multiple Data Mode (SIMD) (.i.e. p GF(2<q>) operations) or Single Instruction Single Data Mode (SISD) (i.e. one GF(2<m>) operation, where m <= p.q.). The choice of p and q is determined by the type of application intended and the level. of performance required. Accordingly, the same realised processor can be programmed for both forward error correction (Reed Solomon Codes, BCH codes) and Cryptography (Advanced Encryption Standard Lirid Elliptic Curve Cryptography) under various performance constraints. The properties of embodiments of processor can also be adapted for use in implementing DSP algorithms over Galois Fields (such as Transforms and adaptive filters). The dual mode design of the GF processor ensures a very high performance regardless of the type of applications. |
