06.Interfacing the QDR to the XILINX SPARTAN-II FPGA.pdf Interfacing the QDR to the XILINX SPARTAN-II FPGA QDR: An Introduction For more details on the QDR refer to the application note “QDR: The Next Generation High-Performance Networking The explosive growth of the internet is boosting the demand SRAM.” for high-speed data communications systems. This has led to the evolution of faster processors and is driving the speed of CY7C1302 the interfacing peripherals higher. While the processors in Figure 1 shows the block diagram of the CY7C1302 QDR these systems have evolved in performance, static memories device. have been unable to keep up the pace. Newer SRAM archi- tectures have evolved to……
