【应用笔记】AN461:在Stratix III和Stratix IV器件中实现QDRII+和QDRII SRAM接口设计指南(AN 461: Design Guidelines for Implementing QDRII+ and QDRII SRAM Interfaces in Stratix III and Stratix IV Devices) QDRII+ and the QDRII SRAM devices are ideally suited for bandwidth– intensive and low-latency applications such as controller buffer memory, look-up tables (LUTs), and linked lists. QDRII+ and QDRII SRAM memory architecture features separate read and write ports operating twice per clock cycle to deliver a total of four data transfers per cycle.
