3.6.3. Avalon Streaming Interface Data Transfer Timing

Figure 12. Avalon Streaming Interface Timing with READY_LATENCY=0

The source provides data and asserts valid on cycle 1, even though the sink is not ready. The source waits until cycle 2, when the sink does assert ready, before moving onto the next data cycle. In cycle 3, the source drives data on the same cycle and because the sink is ready to receive it, the transfer occurs immediately. In cycle 4, the sink asserts ready, but the source does not drive valid data.
