How to Design a High-Speed Memory Interface

Course Description

This course teaches hardware designers who are new to high-speed memory I/O to design a memory interface in AMD 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.
