Title: Serial transmission system
Inventor: HARADA YOSHIHISA
IPC: H04L12/42
Filed: 1990-04-27
Abstract: PURPOSE:To facilitate the data transmission between plural computers by connecting shift registers in a ring, circulating a data while being shifted one by one bit, inputting and outputting a data in serial transmission form. CONSTITUTION:A data propagation delay time in a transmission line B is disregarded in a system where distance among computers is small. Thus, shift registers F1-Fn inserted in series with the transmission line B act like a substantial transmission line and the sent data is stored in the shift registers F1-Fn and the data is circulated synchronizingly while being shifted one by one bit each. When a data frame is generated, whether or not the shift register in the input output interface generating the frame is idle is discriminated and whether or not the shift register of the input output interface of a preceding stage is idle is discriminated. Even when the length of the data frame is set longer than a bit length of the shift registers F1-Fn, since no data collision takes place, it is possible to send plural data in one data frame. A1-An: computer, C1-Cn: input output interface.
