8.4. 3D LUT IP Registers

The 3D LUT IP allows run-time control and LUT programming via the CPU interface.
The register map provides access to:
  • Build parameters such as LUT size and bits per color.
  • A control interface that allows you to enable or bypass the LUT. Also, it allows you to toggle buffers when you turn on Double buffered for the LUT.
  • A RAM interface that allows programming of the LUT’s 8 sub-RAMs during run time and reading their contents if you turn on LUT read interface.
Table 38.  3D LUT IP register mapUnless stated, all the registers are 32-bit wide.
