Function Documentation

int XSys_Init	(	XPeriph *	pPeriph,
		XVprocSs *	pVprocss
	)

This function is the system level initialization routine.

It in turn calls each of the included subsystem initialization function

Parameters

pPeriph	is a pointer to the peripherals instance
pVprocss	is a pointer to the video proc subsystem instance

Returns

• XST_SUCCESS if init. was successful.
• XST_FAILURE if init. was unsuccessful.

Note

None.

void XSys_ReportSystemInfo	(	XPeriph *	pPeriph,
		XVprocSs *	pVprocss
	)

This function reports all the IP's included in the system design.

It calls each subsystem API to report its child nodes

Parameters

pPeriph	is a pointer to the peripherals instance
pVprocss	is a pointer to the video proc subsystem instance

Returns

None

Note

None.

int XSys_SetStreamParam	(	XVprocSs *	pVprocss,
		u16	Direction,
		u16	Width,
		u16	Height,
		XVidC_FrameRate	FrameRate,
		XVidC_ColorFormat	cfmt,
		u16	IsInterlaced
	)

This function is to set vpss stream parameters.

Parameters

pVprocss	is a pointer to the video proc subsystem instance
Direction	defined if parameters are to be applied to Input or output stream
Width	is stream width
Height	is stream height
FrameRate	is stream frame rate
cfmt	is stream color format

Returns

XST_SUCCESS - if the stream configuration is proper XST_INVALID_PARAM - if the stream configuration is not proper

Note

None.
