Abstract: A generator may include a monitoring unit, an engine unit and/or a register. The monitoring unit may selectively extract at least a portion of data to be transmitted to, or received from, an external communication device. The engine unit may generate an error check code using a polynomial expression or a checksum according to a transmission format associated with the extracted data. The register may store the generated error check code.

Abstract: Respective memory locations are assigned for respective edges linking processing nodes of a decoder comprising a plurality of processing nodes. The decoder is applied to a coded input signal to generate a decoded output signal, wherein edge values are iteratively retrieved from and provided to the memory locations such that multiple ones of the memory locations are simultaneously accessed in a processing node operation. The processing nodes may comprise variable nodes and check nodes and the edges comprise edges linking the variable and check nodes. The invention may be embodied as methods, apparatus and computer program products.
