Runtime configurable virtual video pipeline
View Patent ↗A multiple-pipeline system ( 300 ) includes a pool ( 330 ) of auxiliary function blocks (A-E 335 ) that are provided as required to select pipelines. Each pipeline ( 320 ) in the multiple-pipeline system ( 300 ) is configured to include a homogeneous set of core functions (F 1 -F 6 ). A pool ( 330 ) of auxiliary functions (A-E 335 ) is provided for selective insertion of auxiliary functions (A-E 335 ) between core functions (F 1 -F 6 ) of select pipelines. Each auxiliary function includes a multiplexer that allows it to be selectively coupled within each pipeline.
