Performance Gain with Page-based interleaving over Bank-based interleaving

Performance Gain with Page-based interleaving over Bank-based interleaving

Post by ryeun » Wed, 27 Aug 2003 05:02:42


I'm using 8260. According to Motorola's manual, page-based interleaving
would give highest performance. Has anyone done any benchmarking to
determine the percentage gain when switched to page-based interleaving?

What about with page-based interleaving working with Page mode select to
leave a page open until page miss or refresh (rather than back-to-back mode)?

I could have done the experiment myself and figure out any gain we may get.
Unfortunately, we ran into some hurdles, and I need to see if the gain is
worth the pain/cost in overcoming that hurdle.

Any feedbacks would be appreciated.
Thanks,
Raymond

I don't konw about perfomance, but with page-based you could increase SDRAM
size without changing PCB-design.
