VIP Deinterlacer in Motion Adaptive Mode Questions

Hi, I have a couple of questions regarding the use of the Altera Deinterlacer in Motion Adaptive mode. How much memory bandwidth does the core require (assuming I use double buffering)?...

Hi Jake,

Thanks - it is definitely useful!

If your local memory width is 128 bits (if you are using 32-bit DDR2 memory), would it make any sense to increase the memory data width of the deinterlacer to a value above 128 (256 is the next value). I guess this would result in larger burst transfers which would increase efficiency (maybe slightly), but would also increase internal memory requirements?

Altera should consider putting some memory bandwidth requirements information in the user guide. Especially for this core where the internal working of the core is not so obvious to the user.

Regards,

Niki
