The following table summarizes the signals, which are either shared by, or not part of the dedicated AXI4-Stream, memory mapped AXI4 data, or AXI4-Lite control interfaces.
| Signal Name | I/O | Width | Description |
|---|---|---|---|
| ap_clk | I | 1 | Video core clock |
| ap_rst_n | I | 1 | Video core active-Low clock enable |
| interrupt | O | 1 | Interrupt Request Pin |
| field_id | O (Frame Buffer Read) | 1 | Field polarity (only available when interlaced support is selected) |
| I (Frame Buffer Write) |
The ap_clk and ap_rst_n signals are shared between
the core, the AXI4-Stream, memory mapped AXI4 data interface, and the AXI4-Lite
control interface.
