VHDL工具实现SDRAM控制器的要点分享在高速实时或者非实时信号处理系统当中,使用大容量存储器实现数据缓存是一个必不可少的环节,也是系统实现中的重点和难点之一。SDRAM(同步动态随机访问存储器)具有价格低廉、密度高、数据读写速度快的优点 2018-01-18 07:21:00 如何使用Verilog实现基于FPGA的SDRAM控制器? 本文提出了...
这样就屏蔽掉了SDRAM操作的复杂性,而其它逻辑模块可通过接口电路对SDRAM进行访问。此外,由于整个SDRAM控制器用VHDL语言编写,只要对其进行简单的修改就可以满足不同的需求,具有很强的灵活性。 参照图2,SDRAM控制器完成的主要功能是对CMD[2:0]的命令字和ADDR端的地址进行解析,产生相应的SDRAM的控制时序。 CLK为输入的...
