Abstract

본 발명은 데이타 병렬처리에서 다수의 채널을 통해 전송되는 데이타들을 다중화하는 장치 및 그 방법에 관한 것으로서, 특히 패킷의 시작을 알리는 코드와 데이타로 구성된 가변적길이를 갖는 패킷들을 여러채널을 통해 전송받아서 패킷들을 본래의 조합순서에 맞게 조합하여 하나의 채널로 전송하기 위한 다중화장치 및 그 방법에 관한 것이다.The present invention relates to an apparatus and a method for multiplexing data transmitted through a plurality of channels in data parallel processing. In particular, a packet having a variable length consisting of a code and data indicating a start of a packet is transmitted through multiple channels. The present invention relates to a multiplexing device and a method for combining the same according to the original combination order to transmit a single channel.
