Gates select ones of said the plurality of memories corresponding to ones of the respective expansion bit positions that contain ‘1’, and an exclusive-OR gate combines outputs of the gates that select. A specialized processing block includes a multiplier stage, and an input stage upstream of the multiplier stage, with such Galois-field reduction circuitry in the input stage with its output selectably connectable to the multiplier stage and selectably connectable to an output of the specialized processing block. A programmable integrated circuit device includes a plurality of such specialized processing blocks, and additional multiplier and additional exclusive OR gates for concatenating a plurality of specialized processing blocks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circuitry and methods for implementing Galois-field reduction","description":"Galois-field reduction circuitry for reducing a Galois-field expansion value using an irreducible polynomial includes a plurality of memories, each for storing a respective value derived from the irre","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9619207","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
