TDA2P-ACD: Max. OutputBlockWidth / OutputBlockHeight in SIMCOP/LDC

Tobias Schulze

Part Number: TDA2P-ACD

Hello Everyone,

I am currently working on a TDA2P usecase that includes LDC which is done by SIMCOP. The according LDC params, e.g. the outputBlockWidth and outputBlockHeight can be set in simcopConfig.ldcConfig.advCfg.

The TRM shows the min. requirements for these two parameters (width must be multiple of 8/16/32, fitting into the outputFrame completely etc.) but I was wondering if there are any max. values that OutputBlockWidth and OutputBlockHeight can be? For performance reasons I want to make those params as big as possible but the usecase crashes when they are too big.. are they restricted by a buffer size or something else?

Regards,

Tobias

Hi Tobias,

You could run the DCC tool and get the optimal output block size for the given lookup table and LDC configuration.
Essentially, output block size depends on the loopup table and is limited by the available internal memory..

Hi Brijesh,

I will take a look into the DCC tool then. There are no theoretical recommendations, like maximizing the width over height, aren't they? At least I didn't find any regarding the max. settings..

Do you know what internal memory exacrly? I assumed the LDC blocks use a dedicated buffer which is limited in size...

Tobias

Hi Tobias,

LDC uses back mapping, which means it maps output to input pixel. Now depending on the LUT, input block memory required for the output block can limit the output block size, due to limited internal memory size..
I exactly don't remember memory size, you could refer to know the memory size.
