说明：  通过循环读写DDR3内存，了解其工作原理和DDR3控制器的写法，由于DDR3控制复杂，控制器的编写难度高，这里笔者介绍XILINX的MIG控制器情况下应用，是后续音频、视频等需要用到SDRAM实验的基础。(Through reading and writing DDR3 memory circularly, we can understand its working principle and the writing method of DDR3 controller. Because of the complexity of DDR3 control, it is difficult to write the controller. Here, the author introduces the application of Xilinx's MIG controller, which is the basis of SDRAM experiment for subsequent audio and video.)

Top module name : SHIFTER (File name : SHIFTER.v) 2. Input pins: SHIFT [3:0], IN [15:0], SIGN, RIGHT. 3. Output pins: OUT [15:0]. 4. Input signals generated from test pattern are latched in one cycle and are synchronized at clock rising edge. 5. The SHIFT signal describes the shift number. The shift range is 0 to 15. 6. When the signal RIGHT is high, it shifts input data to right. On the other hand, it shifts input data to left. 7. When the signal SIGN is high, the input data is a signed number and it shifts with sign extension. However, the input data is an unsigned number if the signal SIGN is low. 8. You can only use following gates in Table I and need to include the delay information (Tplh, Tphl) in your design.
