  • 第1题：

    Interrupts are an important part of embedded

    systems. Consequently, many compiler vendors

    offer an extension to standard C to support interrupts.

    Typically, the keyword is __interrupt. The following

    code uses __interrupt to define an interrupt service

    routine (ISR). Point out problems in the code.

    __interrupt double compute_area (double radius)

    {

    double area = PI * radius * radius;

    printf("\nArea = %f", area);

    return area;

    }

  • 第4题：

    Which of the following statements about teachers' instructions is NOT true?

    A．Instructions should be simple and clear.
    B．Instructions can be long and complicated for students to follow.
    C．Teachers can use body language to assist students to understand.
    D．Instructions should be kept to a minimum during activities.

    答案：B
    解析：
    考查课堂教学中的教师指令语。教师的课堂指令语应简洁明了，这样学生才会明白；切忌长而复杂．这样不便于学生理解，也会影响教学的效率。教师在课堂上应尽量少用母语，必要时可以使用身体语言辅助学生理解。课堂指令语不应过多，教师应最大限度地发挥学生的主观能动性。故选B。

  • 第17题：

    An operating system also has to be able to service peripheral（ ）,such as timers,motors,sensors,communicationdevices,disks,etc.All of those can request the attention of the OS（ ）,i.e.at the time that they want to use the OS,theOS has to make sure it's ready to service the requests.Such a request for attention is called an interrupt.There are twokinds of interrupts:Hardware interrupts and Software interrupts.The result of an inteiTup:is also a triggering of theprocessor,so that it jumps to a（ ）address.Examples of cases where software interrupts appear are perhaps a divide by zero,a memory segmentation fault,etc.So this kind of interrupt is not caused by a hardware event but by a specificmachine language operation code.Many systems have more than one hardware interrupt line,and the hardwaremanufacturer typically assembles all these interrupt lines in an interrupt（请作答此空）.An Interrupt（ ）is a piece of hardware that shields the OS from the electronic details of the interrupt lines,so that interrupts can be queued and none of themgets lost.
