FPGA将从CY7C68013读到的数写入SRAM-FPGA will read a few CY7C68013 write SRAM

反应速度测试小游戏，最小外设cpld游戏，带设计说明书(Reaction speed test games, the minimum peripheral cpld game, with design specifications)

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.

资源描述针对于Virtex5FPGA的DDR2读写测试的完整工程,已测试可以使用，可以根据自己的ddr2配置自行更改。。。。

1 由matlab计算FIR数字滤波器的滤波系数； 2 用VHDL语言设计逻辑电路，再通过QUARTUS II 软件，将各个模块的电路封装成期间，在顶层设计中通过连线，完成整个系统。 (matlab VHDL QUARTUS )
