21.3.1. Full Raster to Clocked Video Converter Interfaces
- Full raster data input interface for video IOs
- Intel clocked video data output interface for video IOs
- Avalon memory-mapped CPU interface
Name | Direction | Width | Description |
---|---|---|---|
vid_clock | Input | 1 | When you select Lite and CVI, this is the video clock for the lite and clocked video outputs, and the streaming full raster input. When you select CVO, the clocked video outputs bus can contain an optional input clock. If you turn on the clocked video output input clock, this signal is a dummy signal retained for Platform Designer connectivity. The IP uses the video clock included in the cv_vid_out 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 that the IP uses. |

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 host 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 writing 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. |

The equation gives the sizes of all tdata widths in these interfaces;
max (floor(((bits per color sample x (number of color planes+1) x pixels in parallel) + 7) / 8) x 8, 16)
The equation gives the data width size:
width = (bits per color sample X number of color planes X pixels in parallel)
The equation gives the data width size:
width = (bits per color sample X number of color planes X pixels in parallel)
