基于FPGA的串口与外部SDRAM通信的电路设计

Design of communication circuit between serial port and external SDRAM based on FPGA

介绍了一种基于FPGA技术实现PC串口与外部SDRAM之间数据传输的方法。给出了各个模块的具体设计方法,以及整体设计的实现,并验证了用FPGA实现PC与外部SDRAM进行串行通信的可行性。

A data transmission method between PC serial port and external SDRAM was realized based on FPGA technology. The structure of the whole system as well as each module was presented in detail. Finally, the possibility of realizing communication between the PC and an external SDRAM that based on FPGA was verified.
