INTERCONNECT COMMUNICATION PACKAGING ERROR-CORRECTING FUNCTION WITHOUT AFFECTING LATENCY IN CASE OF NO ERROR

摘要

PPROBLEM TO BE SOLVED: To achieve interconnect communication mounting an error-correcting function without affecting latency when there occurs no error in a reception apparatus (600) that transfers an output from a transmission apparatus (500) through an external communication path (530) to a next-stage processing circuit (700) connected to the next stage. PSOLUTION: The reception apparatus comprises: a circuit (610) for receiving an input of a reception packet and detecting a portion corresponding to a header; an Invalidation generation circuit (623) which decodes the reception packet, performs error detection and generates an Invalidation signal if any error is detected; a decoding circuit (620) including a buffer (621) capable of holding that reception packet just for a time required for error correction; and an output selection circuit (630) for selecting, using the Invalidation signal, whether to turn the reception packet into a state of speculatively transferring the reception packet to a next-stage processing circuit on the next stage while keeping it as it is without ending reception of the reception packet, or to turn the reception packet into a state of transferring the reception packet after decoding.
