XILINX FPGA内部BRAM资源的应用研究

Application Research on BRAM in XILINX FPGA

XILINX FPGA内部拥有丰富的存储资源BRAM,可以大大简化设计的复杂度,在电子硬件模块设计中得到了广泛应用。BRAM可以用来设计单口存储器、双口存储器和FIFO等,满足数据缓冲和交换等应用需求。简要介绍BRAM的主要接口和功能,结合多年经验,重点描述了使用BRAM过程中异步访问接口设计考虑和双口存储器访问竞争处理等方面应注意的问题,为正确使用BRAM提供参考。

There are rich memory resources BRAM in XILINX FPGA,which can greatly simplify the complexity of design and has been widely used in the design of electronic hardware modules.BRAM can be used to design single port RAM,Dual port RAM and FIFO etc.to meet the system requirement for data buffer and exchange.The paper introduces briefly the main interface and function of BRAM.Then some rules and consideration on BRAM usage,such as asynchronous interface design and conflict avoidance of Dual port RAM,are presented based on practice to guide the application of BRAM.
