6.10.3.1. Avalon® Streaming Demultiplexer IP Input Interface

Each input interface is an Avalon® streaming data interface that optionally supports packets. You can configure the following parameters for the input interface:
  • Data Bits Per Symbol—The bits per symbol is related to the width of readdata and writedata signals, which must be a multiple of the bits per symbol.
  • Data Symbols Per Beat—The number of symbols (words) that are transferred per beat (transfer). Valid values are 1 to 32.
  • Include Packet Support—Indicates whether data packet transfers are supported. Packet support includes the startofpacket, endofpacket, and empty signals.
  • Channel Signal Width (bits)—The number of bits for the channel signal for output interfaces. A value of 0 means that output interfaces do not use the optional channel signal.
  • Error Signal Width (bits)—The width of the error signal for input and output interfaces. A value of 0 means the error signal is in use.
Note: If you change only bits per symbol, and do not change the data width, errors are generated.
