Abstract
A data processing apparatus includes two data transmission paths formed likewise in a loop fashion. These data transmission paths include a plurality of latch registers connected in a cascade fashion respectively and are constituted as a so-called self-running type shift register wherein each data word constituting a data packet is shifted in sequence provided that a pre-stage register is vacant. Data packets are transmitted in the directions reverse to each other on the two loop-shaped data transmission paths an identification data included in each data packet being transmitted is detected in a section defined as a data packet pair detecting section. The detected identification data are compared in a comparing circuit and, one new data packet is produced from the two data packets in a manner that a data packet is joined from one data transmission path to the other data transmission path.
