摘要： A device for receiving data on a plurality of parallel lines wherein the data on specific ones of said parallel lines occur at different rates. The apparatus utilizes clock information obtained with said data. The apparatus further samples each line at a rate at least as fast as the data on any line can be presented but only places the sampled data in scratch pad memory once for each clock occurrence. Upon completion of assembly of each data word, it is transferred to buffer storage memory. The apparatus as described will eliminate or dump data from prescribed sources by placing all undesired data words in an unaccessed or write only place in buffer storage memory while forwarding the desired data words to their appropriate retrievable places in buffer storage memory. A further feature of this device comprises a section which serializes words in a unique manner wherein complete words are placed in a buffer memory and the output of these words occurs in constant byte sized portions which are individually addressed and applied to a byte sized output serializer.
