(1) These sizes are a guide only and vary with different choices of parameters. These numbers are created with the default settings for each device
family, varying only the width of the interface. Generally, the controller uses about 700 LEs while the size of the datapath varies with width and
the amount of pipelining and clocking scheme required.
(2) The controller uses M4K RAM blocks to buffer write data from the user logic. If you select a burst length of 1 (2 on the DDR SDRAM side), this
buffer is not necessary and no memory blocks are used in your variation, regardless of data width.
The performance of the entire system and in general the DDR or DDR2 SDRAM
controller depends upon the number of masters and slaves connected to the Avalon ?
Memory-Mapped (Avalon-MM) interface, which degrades as the number of masters
and slaves connected to it increases. If the number of masters connected to the slave
increases, the size of the arbiter (which is part of the Avalon-MM interface) increases,
which reduces the performance of the system. The DDR or DDR2 SDRAM controller
performance is limited by the frequency of Avalon-MM interface.
There is no latency associated within the Avalon-MM interface, when it transfers the
read or write request to the controller local interface. If there are multiple masters
connected to the DDR or DDR2 SDRAM controller, there may be wait states before
the request from the master is accepted by the controller.
