6.11.2.3. Avalon® Multiplexer IP Parameters

You can configure the following parameters for the Avalon® Multiplexer IP:

Table 178.   Avalon® Multiplexer IP Parameters
Parameter Legal Values Description
Number of Input Ports 2-16 The number of input interfaces that the multiplexer supports
Scheduling Size (Cycles) Up to 512 The number of cycles that are sent from a single channel before changing to the next channel.
Use Packet Scheduling On/Off When this parameter is turned on, the multiplexer only switches the selected input interface on packet boundaries. Therefore, packets on the output interface are not interleaved.
Use high bits to indicate source port On/Off

When this parameter is turned on, the multiplexer uses the high bits of the output channel signal to indicate the origin of the input interface of the data.

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 turned on, bits [5:4] of the output channel signal indicate origin of the input interface of the data, and bits [3:0] are the channel bits that were presented at the input interface.

Use synchronous resets On/Off Turning off means allowing asynchronous resets, turning on means reset is synchronized.
