44.3.3. Run-time Settings

If you turn on the Avalon memory-mapped control agent interface, the resolution, interlace settings and test pattern configuration can be adjusted at run time via the register map. Changing settings at run time differs depending on whether the test pattern generator is parameterized to output the full or lite variant of the Intel FPGA streaming video protocol.

Full Variants

When you turn off Lite mode, you can edit any of the test pattern generator settings at any time. The IP does not apply the settings until the start of the next frame after a write to the COMMIT register (address 0x014C). The IP can complete a change to the settings that requires writes to multiple registers without the risk of applying the earlier writes in the sequence one frame before the later writes in the sequence.

The full sequence for register updates for full variants is:

  1. Make the required edits to any subset of the test pattern generator settings in the register map (addresses 0x120 to 0x0128 and addresses 0x0150 and 0x015C to 0x0168).
  2. After the first write to update a setting, the IP asserts bit 1 of the STATUS register (address 0x0140) in the return data for any read to this address.
  3. Write any value to the COMMIT register (address 0x014C) to commit the changes as a coherent set.
  4. Do not make any further edits to the settings until the IP deasserts bit 1 of the STATUS register at the next field boundary after the write to the COMMIT register. If the IP has any updates to the test pattern settings (address 0x0120 to 0x0128, and 0x0150), at this point the field index is reset to 0. The field index is a count of the number of frames since the last update. The interlace sequence is reset to start at F0 or F1, as specified in the register map.
  5. When the IP deasserts bit 1 of the STATUS register, you may make further settings updates.

The COMMIT mode register gates the application of updates to all registers except the CONTROL register (address 0x0148). The CONTROL register allows you to stop and start the IP output at frame boundaries. The IP applies updates to the CONTROL register at the next field boundary, regardless of whether you write to the COMMIT register.

Lite mode

If you turn on Lite mode the IP has no COMMIT register functionality. The recommended flow for updating the test pattern generator settings is:

  1. Write 0 to the CONTROL register (address 0x0148) to stop the test pattern generator at the next field boundary.
  2. Read the STATUS register (address 0x0140) until bit 0 is de-asserted, indicating that the test pattern generator is in an idle state between fields.
  3. Make the required edits to any subset of the test pattern generator settings in the register map (addresses 0x120 to 0x0128 and addresses 0x0150 and 0x015C to 0x0168).
  4. Write 1 to the CONTROL register to restart the test pattern generator with the new settings. If the IP has any updates to the test pattern settings (address 0x0120 to 0x0128, and 0x0150), at this point the field index is reset to 0. The interlace sequence is reset to start at F0 or F1, as specified in the register map.
