An apparatus may include a cumulative checksum generator to generate a cumulative checksum for a message, a partial checksum generator to generate one or more partial checksums from one or more respective message segments, and a speculative checksum generator to generate a speculative checksum for each of one or more time slots. In one aspect, a partial checksum corresponding with an initial segment of the message may be generated from at least an initialization vector. A speculative checksum selector may select a first speculative checksum for use in determining whether the message was transmitted without error. The generating of partial and speculative checksums results in a maximally pipe-lined architecture with speed limited only by a minimal cumulative CRC calculation that is fundamentally unavoidable."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speed-optimized computation of cyclic redundancy check codes","description":"Apparatus and methods for generating checksums may process two or more segments of a message in parallel, and may be used with a communications channel having time slots.
