ABSTRACT:
A register data transmission system has a plurality of register devices connected in series to form a data transmission link between a sending device and a receiving device. This register system can function between independent synchronous operating units of a computer such as a pair of data buffers. As data is transmitted, the individual register devices absorb the data as compactly as necessary within limits, to form the data path. Each register device has two data registers and two control flip-flops. The two data registers are the primary and secondary data rank registers. The secondary data rank register only receives data when the primary data rank register cannot receive data. The two control flip-flops are the primary and secondary full-bit flip-flops. Each register device has a clock control. In operation, data travels from the sending device through each register device to the receiving device while a control signal travels from the receiving device to the sending device. Data traveling through the register devices in a transmission path has a pattern analogous to a rippling effect because the timing sequence for the Hold signal from the receiving device travels in a reverse direction through the control flip-flops of the register devices to push the data along in stages. This rippling occurs as a result of each register device holding data in secondary data ranks when the receiving device stops data flow and while the sending device is shutting off.
