43.2.2. Parameters

The following sections list the available options in the IP Parameter Editor.

Functional Parameters

You can configure the following options for the multiplexer:

  • Number of Input Ports—The number of input interfaces that the multiplexer supports. Valid values are 2–16.
  • Scheduling Size (Cycles)—The number of cycles that are sent from a single channel before changing to the next channel.
  • Use Packet Scheduling—When this option is on, the multiplexer only switches the selected input interface on packet boundaries. Hence, packets on the output interface are not interleaved.
  • Use high bits to indicate source port—When this option is on, the high bits of the output channel signal are used to indicate the input interface that the data came from. For example, if the input interfaces have 4-bit channel signals, and the multiplexer has 4 input interfaces, the output interface has a 6-bit channel signal. If this parameter is true, bits [5:4] of the output channel signal indicate the input interface the data is from, and bits [3:0] are the channel bits that were presented at the input interface.

Output Interface

You can configure the following options for the output interface:

  • Data Bits Per Symbol—The number of bits per symbol for the input and output interfaces. Valid values are 1–32 bits.
  • Data Symbols Per Beat—The number of symbols (words) that are transferred per beat (transfer). Valid values are 1–32.
  • Include Packet Support—Indicates whether or not packet transfers are supported. Packet support includes the startofpacket, endofpacket, and empty signals.
  • Channel Signal Width (bits)—The number of bits used for the channel signal for input interfaces. A value of 0 indicates that input interfaces do not have channels. A value of 4 indicates that up to 16 channels share the same input interface. The input channel can have a width between 0–31 bits. A value of 0 means that the optional channel signal is not used.
  • Error Signal Width (bits)—The width of the error signal for input and output interfaces. A value of 0 means the error signal is not used.
