PLD与8051接口的参考设计 Xilinx提供的verilog源代码

说明：  altera 最新的CYCLONE IV的pci-e核的testbench，VHDL源程序。(altera latest CYCLONE IV of the pci-e core testbench, VHDL source code.)

A design on a DE270 FPGA with the use of CCD: a camera DC2 and a TRDB LTM after reading from the SRAM.

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.

rsc递归卷积编码器是turbo码的分量编码器，递归相对于普通的卷积码多了一个反馈，拥有更好地重量谱分布和更加的误码率特性，且码率越高，信噪比越低其优势越明显。利用D触发器组成的rsc生成器，逻辑思维简单，里面包含有测试波形以及测试的结果
