*
|
|
* This header file contains layer 2 API's of the horizontal chroma resampler
|
|
* sub-core driver.The functions contained herein provides a high level
|
|
* implementation of features provided by the IP, abstracting away the register
|
|
* level details from the user
|
|
*
|
|
* <b>H Chroma Resampler IP Features </b>
|
|
*
|
|
* The horizontal chroma resampler IP supports following features
|
|
* - convert YUV422 -> YUV444 and YUV444 -> YUV422
|
|
* - Supports resolution up to 4k2k 60Hz
|
|
* - up to 16 bits color depth
|
|
* - 1, 2 or 4 pixel per clock processing
|
|
*
|
|
* <b>Dependency</b>
|
|
*
|
|
* This driver makes use of the video enumerations and data types defined in the
|
|
* Xilinx Video Common Driver (video_common_vX.x) and as such the common driver
|
|
* must be included as dependency to compile this driver
|
|
|
|
* <b>Initialization & Configuration</b>
|
|
*
|
|
* The device driver enables higher layer software (e.g., an application) to
|
|
* communicate to the hcresampler core.
|
|
*
|
|
* Before using the layer-2 API's user must initialize the core by calling
|
|
* Layer-1 API XV_hcresampler_Initialize(). This function will look for a
|
|
* configuration structure for the device and initialize it to defined HW
|
|
* settings. After initialization Layer-2 API's can be used to configure
|
|
* the core. It is recommended user always make use of Layer-2 API to
|
|
* interact with this core.
|
|
* Advanced users always have the capability to directly interact with the IP
|
|
* core using Layer-1 API's that perform low level register peek/poke.
|
|
*
|
|
* <b> Interrupts </b>
|
|
*
|
|
* This driver does not have any interrupts
|
|
*
|
|
* <b> Virtual Memory </b>
|
|
*
|
|
* This driver supports Virtual Memory. The RTOS is responsible for calculating
|
|
* the correct device base address in Virtual Memory space.
|
|
*
|
|
* <b> Threads </b>
|
|
*
|
|
* This driver is not thread safe. Any needs for threads or thread mutual
|
|
* exclusion must be satisfied by the layer above this driver.
