Function Documentation

void XV_DeintDbgReportStatus

(

XV_Deint_l2 *

InstancePtr

)

This function prints Deinterlacer status on console.

Parameters

InstancePtr

is the instance pointer to the IP instance.

Returns

None

References XV_deinterlacer_Config::BaseAddress, and XV_deinterlacer::Config.

int XV_DeintInitialize	(	XV_Deint_l2 *	InstancePtr,
		u16	DeviceId
	)

This function initializes the core instance.

Parameters

InstancePtr	is a pointer to core instance to be worked upon
DeviceId	is instance id of the core

Returns

XST_SUCCESS if device is found and initialized XST_DEVICE_NOT_FOUND if device is not found

void XV_DeintSetFieldBuffers	(	XV_Deint_l2 *	InstancePtr,
		u64	memAddr,
		XVidC_ColorFormat	cformat
	)

This function sets the deinterlacer cores RD/WR field buffers addresses and color space.

Parameters

InstancePtr	is a pointer to the core instance to be worked on
memAddr	is the buffer address in DDR for RD/WR clients
cformat	is the input stream color format

Returns

None

void XV_DeintStart

(

XV_Deint_l2 *

InstancePtr

)

This function starts the deinterlacer core.

Parameters

InstancePtr

is a pointer to the core instance to be worked on

Returns

None

void XV_DeintStop

(

XV_Deint_l2 *

InstancePtr

)

This function stops the deinterlacer core.

Parameters

InstancePtr

is a pointer to the core instance to be worked on

Returns

None

int XV_DeintWaitForIdle

(

XV_Deint_l2 *

InstancePtr

)

This function waits for the deinterlacer core to report "idle" status.

Parameters

InstancePtr

is a pointer to the core instance to be worked on

Returns

XST_SUCCESS if device becomes idle XST_FAILURE if this routine times out before reading "idle" status

Note

This is intended to be called after XV_DeintStop is called, to wait for all axis and aximm traffic to stop
