VS1010 extension memory

Post by chiyeh.chen »


I have question for extension memory.
We will try to implement AES128CBC/AES128ECB. But memory isn't enough for the feature.
So we would want to extend memory, Is it possible for the VS1010?

Kind regards,

Which memory you ran out and in which stage? Building or loading?

If the VS1010 loader complains running out of memory, the pages are 0: I, 1: X and 2: Y
In the end the build process prints something like: "Total words: I 1107, X 115, Y 49." What did you got?

The practical answer for question of extending memory is that it isn't possible. The exact answer is that I-cache can be mapped as linear memory and get 2kw more but the price is programming difficulty just got harder.
