In this part, the paper mainly discusses the operation principle of SDRAM, chip selection, the diagram of design, the internal module designs in FPGA and the parameter of the board.

The result is that if an internal module is used, the first time the client finds out is when either a compile failure occurs — or when a run time failure occurs because the method signature changed.

If the target service resides within the same module, you could also save some internal name look-up processing.
