3.3. Reed-Solomon II IP Core Interfaces and Signals
The RS II Avalon-ST interface supports backpressure, which is a flow control mechanism, where a sink can indicate to a source to stop sending data.
The ready latency on the Avalon-ST input interface is 0; the number of symbols per beat is fixed to 1.
The clock and reset interfaces drive or receive the clock and reset signal to synchronize the Avalon-ST interfaces and provide reset connectivity. The status interface is a conduit interface that consists of three error status signals for a codeword. The decoder obtains the error symbol value, number of error symbols, and number of error bits in a codeword from the status signals.
