5.3.4. Avalon® Streaming Credit Demultiplexer
The Avalon® Streaming Credit Demultiplexer allows one source to access multiple sinks.
The Avalon® Streaming Credit Demultiplexer:
- Must have a channel signal from the source as an input.
- The channel input from the source must be at least ceil(log2 (NUM_SINKS)) wide, where NUM_SINK is the number of sinks.
For example, if the source connects to 6 sinks, the channel signal from source must be at least 3 bits. The least significant ceil(log2(NUM_SINKS)) bits route data from the source to the appropriate sink. For example, if the demultiplexer connects to 5 sinks (sink0, sink1, sink2, sink3, sink4), and the channel signal is 8-bit wide, with a value on the channel bus of 00010010, data routes to sink2.
- The source is responsible for maintaining packet integrity to any sink.
- During a packet transmission, the source must not change the lower order channel bits, otherwise the sinks may receive incomplete or invalid packets.
- Is available as Avalon Streaming Credit Demultiplexer Intel FPGA IP from the Platform Designer IP Catalog.
