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, LPDDR, and QDRII+. Labs are available for DDR3 on the Kintex™-7 FPGA KC705 board.
