Increase cancel-out LUT size for B/OMTF #347

Closed dinyar closed 8 years ago

dinyar commented 8 years ago

The current LUTs for the matching of ghosts allow a maximum dEta value of 0.162. In the case of the overlap region between BMTF and OMTF dEta for the cancel-out window should be larger.

The LUT should therefore be increased in size by one bit.

Going to try to increase the LUT size for all LUTs for the moment.

dinyar commented 8 years ago

This can be synthesised without problems. The LUTs for the coordinate-based cancel-out now expect 5 bits of eta instead of formerly 4 bits. @thomreis, if it's ok for you I would try to integrate my changes to the emulator with your help on Monday and then we could try to increase the LUT size in the emulator too?

Yes, this can be done.
