Creating High-Speed Memory Interfaces with Virtex-II and Virtex-II Pro FPGAs
Designing high-speed memory interfaces is a challenging task. Xilinx has invested time and effort to make it simple to design such interfaces using the Virtex-IIT and Virtex-II ProT FPGAs. This application note discusses the challenges presented by this task together with various techniques that can be used to overcome them, while illustrating the key concepts in implementing any memory interface. All examples used in this application note assume a DDR-1 interface on an XC2VP20FF1152-6 Virtex-II Pro FPGA. The interface speed is 200 MHz.
