发明名称 SERIAL INPUT/OUTPUT CIRCUIT
摘要 PURPOSE:To release restriction to the number of backward data up to the past by controlling the storage of parallel data in two bidirectional parallel/ serial converters connected by ring coupling through a control part. CONSTITUTION:Input data converted by a serial/parallel (S/P) converter 107 are stored in a storage device 109. The parallel data from the device 109 are stored in the bidirectional P/S converters 111, 110 connected by ring coupling as a continuous bit state through the control part 113. After circulating the stored contents of the converters 111, 110, serial data are outputted from the converter 111, the data of bits following the continuous bits are supplied from the device 109 to the converter 110 through the control part 113 and forward data are infinitely outputted by repeating similar operation. Similarly, backward data can be also infinitely outputted and restriction to the number of backward data can be released.
