A circuit for generating one or more serial bit streams includes a memory coupled to a reformatter, which is in turn coupled to a serializer for converting parallel data to serial data. The memory includes a plurality of words having a known bit width (e.g., 32 bits) for storing one or more serial bit streams. The length of each serial bit stream is generally not an integer multiple of the memory's bit width, causing the last word storing each serial bit stream to contain a gap. The reformatter eliminates each such gap by combining bits from the last word of a bit stream with bits from the first word to provide a completely filled word to the serializer. As operation proceeds, the reformatter continues to combine bits from successive words to ensure that completely filled words are produced. Gaps that formerly appeared when producing serial bit streams are thereby eliminated.
