The highest priority interrupt in the 8085 is the TRAP interrupt.
i need compare between vectored interrupt system and polling
An interrupt is generally initiated by an I/O device, and causes the CPU to stop what it's doing, save its context, jump to the appropriate interrupt service routine, complete it, restore the context, and continue execution. For example, a serial device may assert the interrupt line and then place an interrupt vector number on the data bus. The CPU uses this to get the serial device interrupt service routine, which it then executes as above.A trap is usually initiated by the CPU hardware. When ever the trap condition occurs (on arithmetic overflow, for example), the CPU stops what it's doing, saves the context, jumps to the appropriate trap routine, completes it, restores the context, and continues execution. For example, if overflow traps are enabled, adding two very large integers would cause the overflow bit to be set AND the overflow trap service routine to be initiated.
The peripheral with the highest interrupt priority depends on the hardware and software design of the particular system. In the 8085, the TRAP interrupt has the highest priority. The peripheral connected to TRAP is your choice.
internal interrupt is synchronous with the program while external interrupts are asynchronous.
yes.
The TRAP interrupt is non-maskable.
Nope
The TRAP interrupt can not be masked by software, unless there is hardware in place to allow that, perhaps by anding an output bit with the TRAP request line.
interrupt is a signal caused by I/O devices where as subroutine is a part of the program which is excuted rapidly
Same thing
A J trap is normally tubular and a P trap is brass and does not swivel
