20.5. Color Plane Manager Software API

The IP includes software for run-time control. The IP does not fit any of the generic device models provided by the Nios II HAL and it exposes a set of dedicated accessors to the control and status registers. The IP driver structure inherits the base driver structure so all common methods defined in Video and Vision Processing IPs Software API are applicable.
Note: The software API is only available when you select rearrange for Color plane manager mode. When you select split or merge, the IP has no software API.

Register definition header file: intel_vvp_cpm_regs.h

Include file: intel_vvp_cpm.h
