3.6.1. Avalon Streaming Interfaces in DSP Intel FPGA IP

Avalon streaming interfaces define a standard, flexible, and modular protocol for data transfers from a source interface to a sink interface.

The input interface is an Avalon streaming sink and the output interface is an Avalon streaming source. The Avalon streaming interface supports packet transfers with packets interleaved across multiple channels.

Avalon streaming interface signals can describe traditional streaming interfaces supporting a single stream of data without knowledge of channels or packet boundaries. Such interfaces typically contain data, ready, and valid signals. Avalon streaming interfaces can also support more complex protocols for burst and packet transfers with packets interleaved across multiple channels. The Avalon streaming interface inherently synchronizes multichannel designs, which allows you to achieve efficient, time-multiplexed implementations without having to implement complex control logic.

Avalon streaming interfaces support backpressure, which is a flow control mechanism where a sink can signal to a source to stop sending data. The sink typically uses backpressure to stop the flow of data when its FIFO buffers are full or when it has congestion on its output.
