Disparity mapp code in VHDL

应用背景在本文中，一个高性能和高度优化Rijndael AES算法的硬件实现了设计并实现Xilinx Virtex-5 xc5vlx50FPGA器件。设计采用模块化利用VHDL语言的方法。设计工作正确如图所示。这个所提出的设计的性能进行评估的基础上吞吐量和面积。我们的设计利用了速度339.087兆赫，这意味着吞吐量4.34用399片Virtex-5 FPGA面积Gbps。关键技术本文提出了一种有效的Rijndael算法的硬件实现高级加密标准（AES）加密算法采用最先进的现场可编程门阵列（FPGA）。在非常高速集成电路设计的设计硬件描述语言（VHDL）。时序仿真进行验证所设计的电路的功能。性能评估也做了吞吐量和区域。在国家的最先进的Xilinx Virtex-5实现设计（xc5vlx50ffg676-3）FPGA实现吞吐量4.34千兆位/秒，总共使用了399片。

同步串行数据发送电路SSDT的基本功能是将并行数据转换成串行数据并进行同步发送。系统写入和读出时序完全兼容Intel8086时序。 系统以同步信号开始连续发送四个字节，在发送中出现5个1时插入一个0，在四个数据发送结束而下一次同步没有开始之前，发送7FH，这时中间不需要插入零 -synchronous serial data transmission circuit SSDT the basic function is to convert parallel data into serial and the same this step. System write and read sequential fully compatible Intel8086 timing. Synchronized signal system to start sending four consecutive bytes, in this emerging 5 1:00 insert a 0, at the end of four data sent and the next synchronization not started before, sending seven FH, then the middle is not inserted

1 前大灯可以随意打开和关闭； 2 当汽车左转弯的时候，前左转向灯闪烁，同时左后灯的3盏灯由右往左闪烁； 3 当汽车有转弯的时候，前右转向灯闪烁，同时右后灯的3盏灯有左往右闪烁； 4 当汽车减速或紧急刹车的时候，左后灯和右后等同时闪烁； 5 当汽车在左转弯的同时减速，则前左转向灯闪烁，左后灯的3盏灯由右往左闪烁，同时右后灯都点亮。 6 当汽车在左转弯的同时减速，则前右转向灯闪烁，右后灯的3盏灯有左往右闪烁，同时左后灯都点亮。 -a former headlamps can be opened and closed at will; 2 when the vehicle made a left turn when the former left to lights flickered. Left lights while the three lights flashing from right-go left; 3 when the vehicle is making a turn when a right turn to the former lights flickered. Right after the lights while the three lights are blinking right and left; 4 when the vehicle deceleration or when the emergency brake, Left and right after the lights blink, and so on; 5 when the vehicle made a left turn at the same time to slow down, and then to the left before the lights flickered. Left lights three lights flashing from right-go left, right after the lights are lit. 6 when a car made a left turn at the same time to slow down, and then right before the lights to flick
