This IP core is that of a small, simple SDRAM controller used to provide a 32-bit pipelined Wishbone interface to a 16-bit SDRAM chip.
When accessing open rows, reads and writes can be pipelined to achieve full SDRAM bus utilization, however switching between reads & writes takes a few cycles.
The row management strategy is to leave active rows open until a row needs to be closed for a periodic auto refresh or until that bank needs to open another row due to a read or write request.
This IP supports supports 4 open active rows (one per bank).
