speeding up DDR read in p4080

[nirlevy]

HI,

I have noticed that the read operation from DDR ( i/o mem mapped) is 8 times slower than the write operations.

do you have any suggestions on how can I speed it up for blocks read?

The DDR id configured with SPD ( no ECC no interleaving)

What is method is used for estimate read operations.

Look at the following documents for DDR setting:

and

Have a great day,
Pavel Chubakov
