7.6. Avalon® Streaming Delay Intel® FPGA IP

The Avalon® Streaming Delay Intel® FPGA IP provides a solution to delay Avalon® streaming transactions by a constant number of clock cycles. This IP supports up to 16 clock cycle delays.

Figure 231.  Avalon® Streaming Delay Intel® FPGA IP

The Avalon® Streaming Delay Intel® FPGA IP adds a delay between the input and output interfaces. The IP accepts transactions presented on the input interface and reproduces them on the output interface N cycles later without changing the transaction.

The input interface delays the input signals by a constant N number of clock cycles to the corresponding output signals of the output interface. The Number Of Delay Clocks parameter defines the constant N, which must be from 0 to 16. The change of the in_valid signal is reflected on the out_valid signal exactly N cycles later.
