Detailed Description
One step of a line operation pipeline.
mpix_base_op structs are chained together into a linked list. Each step of the linked list contain a ring buffer for the input data, and a pointer to a conversion function processing it. Along with extra metadata, this is used to process data as a operation of lines.
