How to Design a High-Speed Memory Interface

This course teaches hardware designers who are new to high-speed memory I/O to design a memory interface in Xilinx FPGAs. It introduces designers to the basic concepts of high-speed memory I/O design, implementation, and debugging using 7 series FPGAs. Additionally, students will learn about the tools available for high-speed memory interface design, debug, and implementation of high-speed memory interfaces. The major memory types covered are DDR2 and DDR3. The following memory types are covered on demand: RLDRAMII, LPDDR2, and QDRII+. Labs are available for DDR3 on the Kintex-7 FPGA KC705 board.
