Introduction The Xilinx OPB SDRAM Controller provides a SDRAM Con- troller that connects to the OPB and provides the control interface for SDRAMs. It is assumed that the reader is famil- iar with SDRAMs and the IBM PowerPC™. Features The OPB SDRAM Controller is a soft IP core designed for Xilinx FPGAs and contains the following features: •OPB interface •Performs device initialization sequence upon power-up and reset conditions •Performs auto-refresh cycles •Supports single-beat and burst transactions •Supports various SDRAM data widths (8, 16, and 32 bits) set by a design parameter •Operating frequency >=100MHz OPB SDRAM Controller Design Parameters To allow the user to obtain a OPB SDRAM Controller that is uniquely tailored for their system, certain features are parameterizable in the OPB SDRAM Controller design. This allows the user to have a design that only utilizes the resources required by their system and runs at the best possible performance. The features that are parameteriz- able in the OPB SDRAM Controller are shown in Table 1.
