类型:Soft IP
简短描述:NTSC/PAL Video Display Controller Core
详细描述:

 A semiconductor IP core that implements a video display converter producing standard video data and control signals ready for further processing by an NTSC or PAL broadcast signal encoder. The video data the core produces conforms to the ITU-R BT.601/BT.656 recommendation (formerly CCIR-601 and CCIR-656).

The video display core accepts three different input formats and produces standard 4:2:2 YCbCr pixel data. It also generates all the horizontal and vertical timing periods required for broadcast: horizontal and vertical front porch, back porch, and sync intervals. The core’s output signals are compatible with the popular Analog Devices’ ADV7174/79 or similar NTSC/PAL video encoder chip.

Ready for easy integration with AMBA-based microprocessor systems, the TVOUT-CTRL includes a wrapper that efficiently interfaces the core DMA, FIFO, and control logic functions with the AMBA High-Speed Bus (AHB).

The core is designed for efficient implementation, good performance, and straightforward testing in an ASIC or FPGA SoC design. Typical ASIC results (0.18 μm) show it to require from 14,300 gates for 100 MHz speed to 15,200 gates for 200 MHz.


工艺:0.18 μm
代工厂:UMC
应用:1)portable video systems 2)digital cameras with video output 3)advanced mobile phones with video capabilities
特色:


  • Produces video data that meets the ITU-R BT.601/BT.656 recommendation (without the SAV and EAV features)
  • Accepts display data input in three formats:
  • RBG 24 bit / pixel
  • RBG 15 bit / pixel
  • 4:2:2 YUV (YCrCb)
  • Provides a video data analog converter (VDAC) interface compatible with an Analog Devices ADV7174/79 chip or similar for PAL/NTSC video signal generation
  • Dedicated unidirectional DMA controller with burst transaction support
  • Configurable internal FIFO
  • Produces 4:2:2 YUV (YCbCr) parallel output format
  • Power Save Mode
  • Internal, event stimulated, and interrupt request generation, with masking capability
  • Integrated test mode – core generates color bar without any AHB bus transactions
  • Integrated with AMBA bus:
  • AMBA AHB slave unit to interface with the host controller
  • AMBA AHB master unit to interface with the host memory
  • Designed for efficient implementation and straightforward testing in ASICs or SoCs
