Parallel Cascaded Recursive Filtering on Multi-Core CPUs and GPUs
Haotian Zhai, Bernd-Peter Paris
The companion of this paper reformulated cascaded second-order (biquad) recursive filtering as a block-tridiagonal linear system and developed two parallel solution algorithms, PH…

Fast Cascaded Recursive Filtering via a Block-Matrix Reformulation
Haotian Zhai, Bernd-Peter Paris
The paper reformulates cascaded biquad IIR filters as a block‑Toeplitz linear system and introduces parallel algorithms (partial LU and cyclic reduction) that dramatically reduce s…
