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. * * Software Initialization & Configuration * * 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. * * Interrupts * * 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 * * Virtual Memory * * This driver supports Virtual Memory. The RTOS is responsible for calculating * the correct device base address in Virtual Memory space. * * Threads * * This driver is not thread safe. Any needs for threads or thread mutual * exclusion must be satisfied by the layer above this driver. * * Asserts * * 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. * * Building the driver * * 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. * * Examples * * An example is provided with this driver to demonstrate the driver usage. * * Cache Coherency * * Alignment * * Limitations * * BUS Interface * *
