PURPOSE: An apparatus for detecting and compensating an error of a parallel synchronous signal is provided to compensate a synchronous signal by detecting an error due to a drop-out phenomenon of an input signal in a reset process. CONSTITUTION: An apparatus for detecting and compensating an error of a parallel synchronous signal includes a synchronous signal conversion portion(1), a parallel resister portion(2), a synchronous signal comparing and mixing portion(50), a data shift portion, and a synchronous signal detection portion(5). The synchronous signal conversion portion converts a synchronous signal according to a constant size. The parallel register portion receives the synchronous signal from the synchronous signal conversion portion and output data of n number. The synchronous signal comparing and mixing portion compares the data of n number to a predetermined synchronous signal, mixes compared results, and outputs the flag value. The data shift portion shifts the data of n number according to the flag value. The synchronous signal detection portion corresponds the output data of the data shift portion to the predetermined synchronous signal.
