You will see burst chop when accessing DDR3 SDRAM using Altmemphy based Controller if local_size is set to 1. When local_size=1 ,you will not get Burst Length (BL) of 8 for consecutive addresses, but
i.e. What causes the core to decide to use Burst Chop of 4 vs. Burst of 8? Also, since I have local_burst_size always equal to 2, should I set the Max Avalon-MM Burst Length to 2. What is different in the core if I have this number set to ...
