How Windows 8 manages the Interrupt handler?

When you are running any process then there are instances when some priority interrupt came in middle that can suspend or pause the working of the running process because some non-maskable interrupt put it in waiting list till it get its execution. Therefore, through this article I am explaining you how Windows 8 will manage the various kinds of interrupts?

Management of Interrupts in Windows 8

How Windows 8 manages the Interrupt handler?When any processing calculation is carried out in the computer system then there are circumstances under which interrupts take place in the system which is asynchronous in nature that indicate the event occurrence for the execution of high priority processes which will change the state of running process. The interrupt can either be hardware or software that causes the processor to save the state of execution of process using the interrupt handler in Windows 8 or it is implemented as the set of instructions that can cause the context switching and transfer control from one process to another.

This interrupt technique will leads to the Multi-tasking in Windows 8 according to which multiple users can run the applications at same time using the real time approach in which processor time can be divided in time slots using interrupt-driven approach. The separate interrupts can also be maintained within the separate memory locations in secondary drive which is referred as interrupt request, the short term scheduler will expected to be there in Windows 8 that make the selection of the interrupts using the ready queue which will only transfer the tasks that are required in the system.

The main work of Interrupt management is to avoid the wasting of processor time that will allocate the processor utilization using event management that includes hardware system implementation for control lines which is integrated with sub system memory. The circuitry of Interrupt handling should be there in Windows 8 that leads to Programmable Interrupt Controller for multiplexing of several sources of Interrupt into one or two CPU lines to available memory controller that can be mapped using the system memory address space.

How Windows 8 manages the Interrupt handler?The Interrupt handling in computer system can be categorized into maskable interrupt which can be reversed, which is not of high priority and most of application processes are act as the maskable Interrupt, the non-maskable interrupts cannot be ignored by the CPU, it is used for processes which is of critical importance such that associated bit within interrupt mask register is not there so there is no ignorance of any singular process. For example- the system processes are non-maskable processes which are not ignored or kill by the user, one thing which is ignored by this process is the forceful ending of process.

Furthermore, the Windows 8 partitioned the interrupts as software interrupts which will manages the software programs using system calls and can be checked using the task manager that will show you list of currently running processes in system and other interrupt are act as the hardware interrupt which is unwanted and created using electrical interference of interrupt line or through which designated hardware. Moreover, the example of the interrupt is x86 architecture disabling and enabling the memory barrier for the accessing of computer data.
