Function Documentation

void XVDemosaic_InterruptHandler

(

XV_demosaic *

InstancePtr

)

Interrupt handler for the Demosaic IP core.

This handler clears pending interrupts and determines if the source is a frame done or frame ready signal. If the interrupt is valid, it calls the registered callback function for the corresponding event.

Parameters

InstancePtr

Pointer to the Demosaic IP instance that just interrupted.

Returns

None

Note

The application is responsible for connecting this function to the interrupt system and providing callbacks using XVDemosaic_SetCallback() during initialization phase.

void XVDemosaic_SetCallback	(	XV_demosaic *	InstancePtr,
		u32	HandlerType,
		void *	CallbackFunc,
		void *	CallbackRef
	)

Installs an asynchronous callback function for the given handler type.

This function registers callback functions for different interrupt events. Supported handler types include frame done (XVDEMOSAIC_HANDLER_DONE) and frame ready (XVDEMOSAIC_HANDLER_READY) events.

Parameters

InstancePtr	Pointer to the Demosaic IP instance.
HandlerType	Type of handler (XVDEMOSAIC_HANDLER_DONE or XVDEMOSAIC_HANDLER_READY).
CallbackFunc	Address of the callback function to be invoked.
CallbackRef	User data item passed to the callback function when invoked.

Returns

None

Note

Invoking this function for a handler that already has been installed replaces it with the new handler.
