SDRAM是一种广泛应用于移动、手持设备的存储芯片,它一次只能允许一个外设对其进行读写,对其正确的控制关系到整个系统的正常工作,因此,如何合理地分配外设对SDRAM的读写控制权至关重要.该文在图像拍摄显示基础上进行改进,添加串口对SDRAM的控制模块,用verilog硬件描述语言设计一个串口传送模块,将SDRAM中存储的数据通过串口传送到PC机上,协议简单,所需资源少,可以实现较高速传送.

SDRAM is a kind of memory chips widely used in mobile, handheld devices, which can only allow one peripheral to read or write at a time. The operation of SDRAM determines whether the entire system can work normally or not.So, It is very important to allocate read and write control power on the SDRAM reasonably. We make an improvement based on the image capture and display by adding a control module for the serial port to read from SDRAM, and we use Verilog hardware descrip?tion language to design a serial transmission module, to transmit the data stored in the SDRAM to the PC. The protocol of serial communication is simple, and it needs little resources, and it can achieve a high speed transmission.
