  • Data generator providing large amounts of data of arbitrary word length
    Patent number: 8154431
    Abstract: A waveform memory 66 stores data streams with each data stream having M-bit parallel data. A sequence memory 60 stores sequence information and data discard information on the amount of data to discard from the last data in each data stream. A sequencer 62 and a waveform memory controller 64 access the waveform memory 66 to provide the data streams using the sequence information. A barrel shifter 68 shifts data in the data stream according to the number of effective data of the last parallel data in the previous data stream if the number of the effective data is less than M. A data shift controller 100 generates data enables indicating whether the data in the data stream are effective or not based on the data discard information. A combiner 72 combines the effective data in the data stream using the data enables.
