Function Documentation

pvaAlgosImageProcessorDeInit()

pvaAlgosError_t pvaAlgosImageProcessorDeInit

(

pvaAlgosImageProcessorContext_t *

imageProcessorContext

)

Frees the internal objects and the ImageProcessorContext object.

Parameters

[in]

imageProcessorContext

The pointer to a pvaAlgosImageProcessorContext_t object that stores the internal parameters needed for Image Processor

Returns

pvaAlgosError_t The completion status of the operation. Its value is pvaAlgosStatusSuccess if the operation is successful

pvaAlgosImageProcessorGetContext()

pvaAlgosError_t pvaAlgosImageProcessorGetContext

(

pvaAlgosImageProcessorContext_t *

imageProcessorContext

)

Initializes ImageProcessorContext object and stores it in the context structure.

Parameters

[in]

imageProcessorContext

The pointer to a pvaAlgosImageProcessorContext_t object that stores the internal parameters needed for Image Processor

Returns

pvaAlgosError_t The completion status of the operation. Its value is pvaAlgosStatusSuccess if the operation is successful

pvaAlgosImageProcessorInit()

pvaAlgosError_t pvaAlgosImageProcessorInit	(	pvaAlgosImageProcessorContext_t *	imageProcessorContext,
		pvaAlgosImageProcessorConfig_t *	imageProcessorParams
	)

Initializes the necessary values for the internal objects in ImageProcessorContext object.

Parameters

[in]	imageProcessorContext	The pointer to a pvaAlgosImageProcessorContext_t object that stores the internal parameters needed for Image Processor
[in]	imageProcessorParams	The pointer to a pvaAlgosImageProcessorConfig_t object that stores the configuration parameters for Image Processor

Returns

pvaAlgosError_t The completion status of the operation. Possible values are:

• pvaAlgosStatusSuccess if the operation was successful.
• pvaAlgosStatusInvalidParameter if the parameter is invalid.

pvaAlgosImageProcessorProcess()

pvaAlgosError_t pvaAlgosImageProcessorProcess	(	pvaAlgosImageProcessorContext_t *	imageProcessorContext,
		pvaAlgosImageProcessorIOBuffer_t *	imageProcessorBuffers,
		cupvaStream_t *	instanceStream,
		int	execTimeout
	)

Sets the I/O Buffers to the internal objects and runs the Image Processor.

Parameters

[in]	imageProcessorContext	The pointer to a pvaAlgosImageProcessorContext_t object that stores the internal parameters needed for Image Processor
[in]	imageProcessorBuffers	The pointer to a pvaAlgosImageProcessorIOBuffer_t object that stores the I/O Buffers that change each frame
[in]	postFence	The pointer to a cupvaFence_t object needed for the synchronization across instructions sent to the PVA Engine
[in]	instanceStream	The pointer to a cupvaStream_t object needed to submit instructions to the PVA Engine

Returns
