Streaming and block processing

Why block APIs matter

DSP filters are often run in blocks in real systems, while examples and tests are often written as one-shot array operations. lattice-dsp provides helper classes to make the block path explicit and testable.

BlockProcessor

BlockProcessor wraps a stateful processor and feeds an input signal in fixed chunks. It returns a BlockResult containing the concatenated output and per-block metadata.

AdaptiveBlockProcessor

AdaptiveBlockProcessor is similar but accepts desired/reference signals for adaptive filters. It is used to test that streaming adaptation remains stable and close to one-shot adaptation.
