<p>PURPOSE:To provide a coincidence detection output circuit for multi-frame data whose processing time is short without the need for data transfer with respect to the coincidence detection output circuit for multi-frame data outputting an output of the multi-frame data when same multi-frame data are consecutive for n-times in the case of reception of the multi-frame data of multi-frame configuration where m-frame is equal to 1 multi-frame. CONSTITUTION:RAMs are formed to be of double buffer configuration and both RAMs 1, 2 are used to detect the coincidence of multi-frame data where m-frames are equal to 1 multi-frame simultaneously over all frames, a data mis-match detection circuit 5 always monitors outputs of m-frame coincidence detection circuits 3, 4 to compare data coincidenct consecutively for n-times in the unit of multi-frames with data coincident consecutively for n-times newly thereby detecting dissidence thereby outputting multi-frame data.</p> |
