Abstract

PURPOSE:To make the correct detection of a clock fault possible despite the occurrence of said fault in a data buffer by comparing data and sequence information and checking the justness of the output data. CONSTITUTION:The data which is being inputted is constituted as bits #0b, #1b,... and a parity bit (p), and is successively shifted in synchronization with clocks. A counter 5 is provided to add sequence information S to the input data and shift the data and the sequence information S. The output data is compared with the sequence information S' made by a counter 6 in a comparator 7, whereby the justness of the output data is checked.
