43.3.2. Parameters
Functional Parameters
You can configure the following options for the demultiplexer as a whole:
- Number of Output Ports—The number of output interfaces that the multiplexer supports. Valid values are 2–16.
- High channel bits select output—When this option is on, the high bits of the input channel signal are used by the de-multiplexing function and the low order bits are passed to the output. When this option is off, the low order bits are used and the high order bits are passed through.
The following example illustrates the significance of the location of these signals. In the Select Bits for De-multiplexer figure below there is one input interface and two output interfaces. If the low-order bits of the channel signal select the output interfaces, the even channels goes to channel 0 and the odd channels goes to channel 1. If the high-order bits of the channel signal select the output interface, channels 0–7 goes to channel 0 and channels 8–15 goes to channel 1.
Input Interface
You can configure the following options for the input interface:
- Data Bits Per Symbol—The number of bits per symbol for the input and output interfaces. Valid values are 1 to 32 bits.
- 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 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 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 not used.
