【应用笔记】Stratix和Stratix GX器件QDR SRAM Controller参考设计(QDR SRAM Controller Reference Design for Stratix & Stratix GX 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 increased 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, SRAM performance has not kept pace. New SRAM architectures are evolving to support the highthroughput requirements of current systems. One such architecture is quad data rate (QDR) SRAM, which provides more than four times the bandwidth of other SRAM architectures.
