FPGA中QDRII+SRAM FIFO接口设计

Design of QDRII+SRAM FIFO Interface on FPGA

为了实现模块化设计,缩短FPGA的开发周期,提出了基于Xilinx Virtex-7 FPGA的QDRII+SRAM FIFO接口设计方案。借鉴标准FIFO的设计思想,结合QDRII+SRAM控制器的特点,设计基于QDRII+SRAM控制器的FIFO接口。通过原型机测试,验证了该接口不仅具有标准FIFO的功能,而且具有存储空间大等优势。

To realize modularized design and shorten FPGA design lifeeycle, a design scheme of QDRⅡ ＋ SRAM FIFO interface based on Virtex-7 FPGA is presented. In view of the standard FIFO design ideas and combining features of QDRⅡ ＋ SRAM controller, a QDRⅡ ＋ FIFO interface based on QDRⅡ ＋ SRAM controller is designed. The result of test on prototype machine demonstrates that the module has effective function of standard FIFO and advantage of large storage space.
