摘要：PURPOSE:To improve the accuracy for transmission of data in a data FIFO.CONSTITUTION:A data FIFO of a data shift register DSR 12 and is provided with a paritygenerating circuit 13 which generated a parity of the data when the data are fetched by aDSR 34 of the 1st stage. Then a parity DSR 14 covering several stages is provided so that
the parity generated by the circuit 13 is transmitted through the DSR parts together withthe data. Furthermore a parity error detecting circuit 15 is added to check a parity errorby comparing the parity added by the circuit 13 with the parity which is newly generatedfrom the data on the final stage when the data are outputted from the DSR of the finalstage.
