19.4. TMO IP Registers

The TMO IP allows run-time configuration parameters via AXI4-Lite CPU register interface.

The IP offers the following categories of run-time configuration parameters:

  • Flow control parameters that allow you to put the TMO IP into either reset, bypass, or operational mode.
  • Status and debug parameters that provide information about compile-tile parameters and on-the flight status of the TMO IP
  • Video configuration parameters that allow you to configure the input video frame geometry
  • Image statistics collection parameters that allow you to configure the tile’s dimension

Bits Description
31

Soft-reset bit. When set to 1 the TMO IP is in reset.

2

Swap region bit for region of interest mode.

0: Process inside of the selected region and bypass outside.

1: Process outside of the selected region and process outside.

The IP ignores this bit in bypass mode.

1

Region of Interest bit. Set to 1 to put the TMO IP in region of interest mode. Swap region bit determines whether inside or outside of the region of interest is processed or bypassed.

The IP ignores this bit in bypass mode.

0 Bypass bit. Set to 1 to put the TMO IP into bypass mode.
