Description: sdram控制器
这里考虑将SDRAM控制器结合目前项目开展来做相应的模块,而不做SDRAM通用控制器,这样也是考虑了FPGA的器件资源而采取的措施。同时编写的逻辑简单,没有多余的逻辑资源有利于提高控制器的速度,满足最后的设计要求。-SDRAM controller here consider SDRAM controller current projects do the corresponding module, but not so common SDRAM controller, as well as consider the FPGA device resources and the measures taken. While the preparation of simple logic, the logic is no spare resources to improve the speed controller to meet the final design requirements. Platform: |

Description: 通过 UART 读写 SDRAM verilog 源代码
通过 UART 的接口发送命令来读写 SDRAM
命令格式如下:
00 02 0011 1111 2222
00: 写数据
02: 写个数
0011: 写地址
1111 2222: 写数据, 是 16 bit, 每写完一个数据,向串口发送 FF 回应;
输出: FF FF
01 03 0044
01: 读sdram
03: 读的个数
0044: 读的地址
输出: xxxx xxxx xxxx
sdram 在 0044 0045 0046 处的数据;
sdram 使用的是 K4S161622D.pdf
系统时钟 25m, 通过 PLL 得到 SDRAM clk 100m
sdram controller clk 100m, 前者相对后者2ns 相移 -Read and write through the UART SDRAM verilog source code through the UART interface to send commands to SDRAM read and write command format is as follows: 0,002,001,111,112,222 00: Write Data 02: Write the number of 0011: write address 11112222: write data, is 16 bit, each completed a data, respond to the serial port FF output: FF FF 01 03 0044 01: Reading sdram 03: 0044 the number of read: Read the address output: xxxx xxxx xxxx sdram at 004,400,450,046 at the data sdram use system clock is K4S161622D.pdf 25m, obtained by PLL SDRAM clk 100m sdram controller clk 100m, the former phase shift relative to the latter 2ns Platform: |
