Part III Figure 2a shows a circuit for a full adder, which has the inputs a, b, and ci, and produces the outputs s and co. Parts b and c of the figure show a circuit symbol and truth table for the full adder, which produces the two-bit binary sum cos = a + b + ci. Figure 2d shows how four instances of this full adder entity can be used to design a circuit that adds two four-bit numbers. This type of circuit is usually called a ripple-carry adder, because of the way that the carry signals are passed from one full adder to the next. Write VHDL code that implements this circuit, as described below. 2

该RFID标签被用作用于帐户的特定用户的一个唯一的标识。当通过收费站的车辆驱动器，它的驱动程序提示您扫描自己的RFID标签。如果标识（串行标签的数目，即，12字节的数据）相匹配与已经存储在系统中的之一，收费金额是从他的账户中扣除。在此之后，该车辆获取即时访问以驱动通过。

基于ARM的温度显示程序，可以在OCM12864上显示温度变化

本系统利用集成智能温度传感器测量温度，采用光纤传输温度信号。系统由单片机（HT46R24）控制温度传感器（DS18B20）的温度采集。当有采集温度的指令的时候，才启动温度传感器并采回其数据，在没有进行温度采集的时候，将通过抬高温度传感器的地，关断其工作电源，如此可以降低系统的功耗。系统将每一次采集回来的数据与前一次的数据比较，若温度变化超限或温升超标，立即发送上述温度值；否则，累加到采集了一定的次数，再向主机发送最新温度值。-The system uses an integrated smart temperature sensors measure temperature, using optical fiber transmission temperature signal. System consists of microcontroller (HT46R24) controlling the temperature sensor (DS18B20) the temperature of collection. When a collection of instructions, when the temperature before start-up temperature sensors and taken back to its data, collected in the absence of the temperature when the temperature sensor will raise, the turn-off the power of their work, so you can reduce system power consumption. The system will come back every time collecting data and previous data comparison, if the temperature changes or temperature exceeding overrun immediately send the temperature value otherwise accumulate to collect a certain number of times, again
