How does an interrupt capable I/O device improve system efficiency?

Expert Solution

Improving generally I/O efficiency can limit both devices I/O and genuine CPU time. The methods recorded in this point can altogether enhance efficiency in numerous applications.

An I/O stream issues limit the most extreme speed of execution by being the slowest procedure in an executing program. In a few programs, I/O is the bottleneck that keeps an enhancement in run-time performance. The way to soothing I/O issues is to diminish the genuine measure of CPU and I/O device time associated with I/O.

The issues can be caused by at least one of the accompanying:

An emotional decrease in CPU time without a relating enhancement in I/O time
Such coding practices as:
Pointless organizing of information and another CPU-escalated handling
Pointless exchanges of the middle of the road results
Wasteful exchanges of little measures of information
Application prerequisites

Enhanced coding practices can limit genuine device I/O, and the real CPU time. Intel offers programming answers for framework wide issues like limiting device I/O delays.

Problem 2. Interrupt-driven I/O (20 pt.) Consider a system employing interrupt-driven I/O for a particular device that transfers data at an average of 2000 bytes/sec on a continuous basis. a. Assume that interrupt processing takes about 200 usec (i.e., the time to jump to the interrupt service routine (ISR), execute it, and return to the main program). Determine what fraction of processor time is consumed by this I/O device if it interrupts for every byte. b. Now assume that the...

Consider a device driver that manages the I/O to a specific device. Multiple threads in the system need to read information from the device. The device can only support one I/O command at a time. Previous I/O commands must complete before a new one is issued. Assume the device can be read using a readDevice( what ) method. Write a read( what ) method to be called by any thread in the system that wants to read something from the...
