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。

全自动洗衣机的控制器。 1.洗衣机的工作步骤为洗衣、漂洗和脱水三个过程，工作时间分别为：洗涤10秒，漂洗5秒，脱水5秒； 2.用一个按键实现洗衣程序的手动选择：A、单洗涤；B、单漂洗；C、单脱水；D、漂洗和脱水；E、洗涤、漂洗和脱水全过程； 3.用显示器件显示洗衣机的工作状态（洗衣、漂洗和脱水），并倒计时显示每个状态的工作时间，全部过程结束后，应提示使用者； 4.用一个按键实现暂停洗衣和继续洗衣的控制，暂停后继续洗衣应回到暂停之前保留的状态； (Automatic washing machine controller. 1 washing machine work steps for the laundry, rinsing and dehydration three processes, working hours are as follows: washed for 10 seconds, rinse for 5 seconds, dehydrated five seconds 2 with a button to manually select the program to achieve laundry: A, single-washing B, single rinse C, a single dehydration D, rinsing and dehydration E, washing, rinsing and dehydration the whole process 3 with a display device display the working status of washing machine (laundry, rinsing and dehydration), and each state countdown show working hours, after the whole process should prompt the user 4 laundry with a button to pause and continue control of laundry, laundry should be back after a pause pause before continuing to retain the state )
