|
|
* @file xrgb2ycrcb.h
|
|
*
|
|
* This header file contains identifiers and register-level driver functions (or
|
|
* macros), range macros, structure typedefs that can be used to access the
|
|
* Xilinx Rgb2YCrCb core instance.
|
|
*
|
|
* The RGB to YCrCb Color-Space Convertor core is a simplified 3x3 matrix
|
|
* multiplier converts three input color samples to three output samples in a
|
|
* single clock cycle. The core supports four common format conversions as well
|
|
* as a custom mode that allows for a user-defined transform. The core is
|
|
* capable of a maximum resolution of 7680 columns by 7680 rows with 8, 10, 12,
|
|
* or 16 bits per pixel.
|
|
*
|
|
* <b>Initialization & Configuration</b>
|
|
*
|
|
* The device driver enables higher layer software (e.g., an application) to
|
|
* communicate to the RGB2YCRCB core.
|
|
*
|
|
* XRgb2YCrCb_CfgInitialize() API is used to initialize the RGB2YCRCB core.
|
|
* The user needs to first call the XRgb2YCrCb_LookupConfig() API which returns
|
|
* the Configuration structure pointer which is passed as a parameter to the
|
|
* XRgb2YCrCb_CfgInitialize() API.
|
|
*
|
|
* <b> Interrupts </b>
|
|
*
|
|
* The driver provides an interrupt handler XRgb2YCrCb_IntrHandler for handling
|
|
* the interrupt from the RGB2YCRCB core. The users of this driver have to
|
|
* register this handler with the interrupt system and provide the callback
|
|
* functions by using XRgb2YCrCb_SetCallBack API.
|
|
*
|
|
* <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.
|
|
*
|
|
* <b> Asserts </b>
|
|
*
|
|
* Asserts are used within all Xilinx drivers to enforce constraints on argument
|
|
* values. Asserts can be turned off on a system-wide basis by defining, at
|
|
* compile time, the NDEBUG identifier. By default, asserts are turned on and it
|
|
* is recommended that users leave asserts on during development.
|
|
*
|
|
* <b> Building the driver </b>
|
|
*
|
|
* The XRgb2YCrCb driver is composed of several source files. This allows the user
|
|
* to build and link only those parts of the driver that are necessary.
|
