Interrupts are an important part of embeddedsystems. Consequently, many compiler vendorsoffer an extension to standard C to support interrupts.Typically, the keyword is __interrupt. The followingcode uses __interrupt to define an interrupt serviceroutine (ISR). Point out problems in the code.__interrupt double compute_area (double radius){double area = PI * radius * radius;printf("\nArea = %f", area);return area;}

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.A.vector
B.array
C.queue
D.ist
