Final answer:
The statement that interrupt checking is typically carried out at various times during the execution of a machine instruction is true. Interrupts can occur at several points during an instruction cycle, and it is the CPU's job to handle these based on its architecture.
Step-by-step explanation:
Interrupt checking is often carried out at various times during the execution of a machine instruction.
This statement is true. During the execution cycle of an instruction, the central processing unit (CPU) may frequently check for interrupts.
An interrupt is a signal sent by hardware or software to the CPU, which can cause the CPU to temporarily halt the current process, save its state, and execute a function called an interrupt handler to deal with the event that caused the interrupt.
After the interrupt has been handled, the CPU can resume the interrupted task.
There are several points during the instruction cycle when interrupt checking might occur, such as before instruction fetch, after instruction execution, and at specific points during complex instruction execution. The precise timing of when interrupt requests are checked and acknowledged depends on the architecture of the processor and the design of its interrupt system.
