Depending on the application, DDR custom interface can be used as a SDR or DDR SDRAM controller. DDR is used to interface any industry standard (SDR or DDR) memory device to a host model (an embedded processor or a system), which drives the core to access SDRAM. The core is verified with SDR, DDR SDRAM devices on one side and a generic system and host interface on the other. The generic system interface is used to initiate write/read transfers, while the host interface is used to configure the core and memory operations.
