基于SOC的SDRAM控制器的分析与设计

Analysis and design of SDRAM controller based on SOC

介绍了SDRAM的内部结构和工作原理,根据时序参数对存取速度的影响,利用优化的状态机对核心控制模块进行设计,减小了存取延时。并通过对波形的仿真,验证了设计的正确性。

This paper introduces the principle and intemal structure of SDRAM. According to the timing paramerer＇ s influence on the access rate, it use optimized FSM to design the core of memory controller. The experiments confirm the true of the design by wave emulator.
