| Question 1 |
Which of the following is an interrupt according to temporal relationship with system clock?
| Maskable interrupt | |
| Periodic interrupt | |
| Division by zero | |
| Synchronous interrupt |
Question 1 Explanation:
Synchronous interrupts are produced by the CPU control unit while executing instructions and are called synchronous because the control unit issues them only after terminating the execution of an instruction.
This interrupt according to temporal relationship with system clock.
Asynchronous interrupts are generated by other hardware devices at arbitrary times with respect to the CPU clock signals..
Maskable Interrupts – Those interrupts whose request can be denied by microprocessor.
eg- RST 1, RST2, RST 5, RST 6.5 etc..
Non maskable Interrupts – Interrupts whose request cannot be denied.
eg -RST 4.5 or TRAP ,RESET IN.
.
Periodic interrupts to cause a software task to be executed on a periodic basis.
This interrupt according to temporal relationship with system clock.
Asynchronous interrupts are generated by other hardware devices at arbitrary times with respect to the CPU clock signals..
Maskable Interrupts – Those interrupts whose request can be denied by microprocessor.
eg- RST 1, RST2, RST 5, RST 6.5 etc..
Non maskable Interrupts – Interrupts whose request cannot be denied.
eg -RST 4.5 or TRAP ,RESET IN.
.
Periodic interrupts to cause a software task to be executed on a periodic basis.
