5. Avalon Streaming Interfaces You can use Avalon Streaming (Avalon-ST) interfaces for components that drive high bandwidth, low latency, unidirectional data. Typical applications include multiplexed streams, packets, and DSP data. The Avalon-ST interface signals can describe traditional streaming interfaces supporting a single stream of data without knowledge of channels or packet boundaries. The interface can also support more complex protocols capable of burst and packet transfers with packets interleaved across multiple channels. Figure 5–1 illustrates a typical application of the Avalon-ST interface. Figure 5–1.

However, if two interfaces provide compatible functions for the same application space, adapters are available to allow them to interoperate.
