|
|
*
|
|
* This is the main header file of Xilinx MVI Video Timing Controller (VTC)
|
|
* device driver. The VTC device detects video signals, independently
|
|
* overrides any one of them, re-generates video signals with +/- delay and
|
|
* with polarity inversion, and generates up to 16 one cycle Frame Sync outputs.
|
|
*
|
|
* The device has the following main features:
|
|
* - Detect video signals:
|
|
* - horizontal sync
|
|
* - horizontal blank
|
|
* - vertical sync
|
|
* - vertical blank
|
|
* - active video
|
|
* - field id
|
|
* - Independently override any one signal.
|
|
* - Re-generate video signals with +/- delay and with polarity inversion.
|
|
* - Generate up to 16 one cycle Frame Sync outputs.
|
|
*
|
|
* For a full description of VTC features, please see the hardware
|
|
* specification.
|
|
*
|
|
* <b>Software Initialization & Configuration</b>
|
|
*
|
|
* The application needs to do following steps in order for preparing the
|
|
* VTC to be ready to process video signal handling.
|
|
*
|
|
* - Call XVtc_LookupConfig using a device ID to find the core
|
|
* configuration.
|
|
* - Call XVtc_CfgInitialize to initialize the device and the driver
|
|
* instance associated with it.
|
|
* - Call XVtc_SetGenerator to set up the video signals to generate,
|
|
* if desired.
|
|
* - Call XVtc_SetPolarity to set up the video signal polarity.
|
|
* - Call XVtc_SetSource for source selection
|
|
* - Call XVtc_SetGeneratorHoriOffset to set up the Generator
|
|
* VBlank/VSync horizontal offsets, if values other than the default are
|
|
* needed
|
|
* - Call XVtc_EnableSync, if generator needs to be synced to the detector
|
|
* - Call XVtc_Enable to enable/start the VTC device.
|
|
*
|
|
* <b>Interrupts </b>
|
|
*
|
|
* The interrupt types supported are:
|
|
* - Frame Sync Interrupts 0 - 15
|
|
* - Generator interrupt:
|
|
* - Generator Active Video Interrupt
|
|
* - Generator VBLANK Interrupt
|
|
* - Detector interrupt:
|
|
* - Detector Active Video Interrupt
|
|
* - Detector VBLANK Interrupt
|
|
* - Signal Lock interrupt:
|
|
* - Active Chroma signal lock
|
|
* - Active Video Signal Lock
|
|
* - Field ID Signal Lock
|
|
* - Vertical Blank Signal Lock
|
|
* - Vertical Sync Signal Lock
|
|
* - Horizontal Blank Signal Lock
|
|
* - Horizontal Sync Signal Lock
|
|
*
|
|
* <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 Vtc driver is composed of several source files. This allows the user
|
|
* to build and link only those parts of the driver that are necessary.
|
|
*
|
|
* <b> Examples </b>
|
|
*
|
|
* An example is provided with this driver to demonstrate the driver usage.
|
|
*
|
|
* <b>Cache Coherency</b>
|
|
*
|
|
* <b>Alignment</b>
|
|
*
|
|
* <b>Limitations</b>
|
|
*
|
|
* <b>BUS Interface</b>
