|
||||
*
|
||||
* This header file contains layer 2 API's of the letter box 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>Letter Box IP Features </b>
|
||||
*
|
||||
* This Letterbox IP supports following features
|
||||
* - Apply black bars (horizontal or vertical) on input stream
|
||||
* - Programmable background colors
|
||||
* - up to 16bits color depth
|
||||
* - 1, 2 or 4 pixel per clock processing
|
||||
* - Input stream up to 4k2k 60Hz
|
||||
*
|
||||
* <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 lbox core.
|
||||
*
|
||||
* Before using the layer-2 API's user must initialize the core by calling
|
||||
* Layer-1 API XV_letterbox_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.

||||
