14.6. Chroma Key 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_chroma_key_regs.h

Include file: intel_vvp_chroma_key.h

Table 155.  Chroma Key IP Software API
Name Description
intel_vvp_chroma_key_init Initialize the Chroma Key instance

intel_vvp_chroma_key_init

Prototype 
int intel_vvp_chroma_key_init(intel_vvp_chroma_key_instance *instance, intel_vvp_core_base base);

base - base address of the register map

Returns

kIntelVvpCoreOk (0) in case of success, a negative error code in case of error

kIntelVvpCoreVidErr if the vendor id of the core is not the IntelFPGA vendor ID (0x6AF7).
