13.3.1. Clocked Video to Full-Raster Converter Interfaces

The Clocked Video to Full-Raster Converter IP has three functional interfaces

  • Clocked video data input interface for video IOs.
  • Full-raster data output interface for video IOs
  • Avalon memory-mapped CPU interface
Table 144.  Clocks and Resets
Name Direction Width Description
vid_clock Input 1

When you select Lite and CVO for CV Bus style, vid_clock is the video clock for the lite and clocked video output inputs, and the streaming full-raster output.

When you select CVI for CV Bus style, vid_clock is a dummy signal retained for Platform Designer connectivity. The IP uses the video clock included in the cv_vid_in conduit.

vid_reset Input 1 Reset for vid_clock domain.
cpu_clock Input 1 Optional control interface clock.
cpu_reset Input 1 Optional control interface reset.
cv_clk_out Output 1 A copy of the video clock the IP uses.
Table 145.   Control Interface This interface is only available if you select True for Memory-mapped control interface.
Name Direction Width Description
av_mm_cpu_agent_address Input 7 Control agent port Avalon memory-mapped address bus. Specifies a word offset into the slave address space.
av_mm_cpu_agent_read Input 1 Control agent port Avalon memory-mapped read signal. When you assert this signal, the control port drives new data onto the read data bus.
av_mm_cpu_agent_readdata Output 32 Control agent port Avalon memory-mapped read data bus. These output lines are used for read transfers
av_mm_cpu_agent_waitrequest Output 1 Control agent port Avalon memory-mapped wait request bus. This signal indicates that the slave is stalling the master transaction.
av_mm_cpu_agent_write Input 1 Control agent port Avalon memory-mapped write signal. When you assert this signal, the control port accepts new data from the write data bus.
av_mm_cpu_agent_writedata Input 32 Control agent port Avalon memory-mapped write data bus. These input lines are used for write transfers.
av_mm_cpu_agent_byteenable Input 4 Control agent port Avalon memory-mapped byte enable bus. These lines indicate which bytes are selected for write and read transactions.
Table 146.  Streaming full-raster video interface
Name Direction Width Description
axi4s_fr_vid_out_tvalid Output 1 AXI4-S full-raster data valid.
axi4s_fr_vid_out_tready Input 1 Optional AXI4-S full-raster data ready.
axi4s_fr_vid_out_tdata Output 20 AXI4-S full-raster data in.
axi4s_fr_vid_out_tlast Output 1 AXI4-S end of full-raster packet .
axi4s_fr_vid_out_tuser[0] Output 21 AXI4-S start of full-raster video frame.
Table 147.  CV-Lite Streaming Video InterfaceThis interface is only available if you select Lite for CV Bus Style.
Name Direction Width Description
cv_vid_in_h Input Pixels in parallel When 1, the video is in a horizontal blanking.
cv_vid_in_v Input Pixels in parallel When 1, the video is in a vertical blanking.
cv_vid_in_h_sync Input Pixels in parallel When 1, the video is in a horizontal synchronization period.
cv_vid_in_v_sync Input Pixels in parallel When 1, the video is in a vertical synchronization period.
cv_vid_in_f Input Pixels in parallel When 1, the video is interlaced and in field 1. When 0, the video is either progressive or interlaced and in field 0.
cv_vid_in_active Input Pixels in parallel When asserted, the video is in an active picture period (not horizontal or vertical blanking). Drive this signal for the correct operation of the IPs.
cv_vid_in_data Input 22 Pixel data.
cv_vid_in_valid Input 1 When 1, the input is valid.
cv_vid_in_ready Output 1 When 1, the IP can accept new data. When 0, no new data can be accepted.
