How much quicker is the BF548 DDR than the BF537 SDRAM?
My code has to histogram an image, which due to the scatter write effect is very slow on a BF537. I have heard that the BF537 SDRAM interface only does a burst of one, is this true? If it is then the cache will actually hinder as it effectively turns one CPU read/write into a cache line of sixteen transfers.
I am considering the BF548, which according to the datasheet timing diagram does bursts of four (or more?) but would like to know if it really will be a lot faster at this before spending the $1000 on the ez-kit.
