23.5. Color Space Converter IP 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.

Register definition header file: intel_vvp_csc_regs.h

Include file: intel_vvp_csc.h
