【应用笔记】APEX II器件QDR SRAM控制器参考设计(QDR SRAM Controller Reference Design in APEX II Devices)
Internet的爆炸式增长已经极大地加速了对高速数据通信系统的需求，这就要求快速的处理器及和外围设备的高速接口。
The explosive growth of the Internet has boosted the demand for highspeed
data communications systems that require fast processors and
high-speed interfaces to peripheral components. While the processors in
these systems have improved in performance, static memories have not
kept pace. New SRAM architectures are evolving to support the high
throughput requirements of current systems. One such architecture is
quad data rate (QDR) SRAM, which can provide bandwidth
improvements more than four times greater than other SRAM
