Abstract
A bitstream generator is described, for placing variable length coding (VLC) data into a fixed width data stream. The bitstream generator includes an input for receiving VLC data; the VLC data may be separated into a value component, and a length component. The bitstream generator also includes an output buffer, a memory module, for storing the VLC data before sending. The bitstream generator also incorporates a backup buffer, which is used to store any overflow data which does not fit in the output buffer. A comparator is used, to determine how much of the VLC data will fit in the output buffer. Any portion of the VLC data which does not fit in the output buffer is stored in the backup buffer.
