Single-port 16/32/64-bit DDR266 Controller

The Single-port 16/32/64 bit DDR266 controller IP core is a DDR266 SDRAM controller AMBA AHB back-end. The controller can interface two 16-, 32- or 64-bit DDR266 memory banks to a 32-bit AHB bus. The controller acts as a slave on the AHB bus where it occupies a configurable amount of address space for DDR SDRAM access. The DDR controller is programmed by writing a configuration register mapped located in AHB I/O address space.

Internally, the core consists of an AHB/DDR controller and a technology specific DDR PHY.
