Interrupt Video Lecture | Embedded Systems (Web) - Computer Science Engineering (CSE)

hi sciences on this video we're going to
see what is interrupts in Turkish it one
of the major topic in the operating
system concepts basically interface a
signal so signal means the signal can be
generated from the hardware particular
hardware or the signal can be generated
from the particulars of program
execution so the first one the signal
from the hardware may be considered a
hardware interrupt signal from the
particular program execution may be
considered as a software entered so so
how this signal can be generated so
during the execution of a particular
program or during the system execution
if any error comes in the particular
part that if the hardware phase example
at the keyboard phase or if the mouse
phase so at that time the particular
signal will be generated from the
particular hardware or the particular
device attached to the system that
signal will be sent to the operating
system this is called
input and example if you are considering
the program execution if the program
phases any error so example if any
hyegyo devices is not working if the i/o
operation is not suitable or not
executed so at that time that particular
Syst that particular program execution
may generate a signal so error signal
will be generated so that particular
signal will comes under that software
interrupt so here software interrupt
also called it
so trap is another name for a software
interrupt so hardware in turn may not be
solved because the hardware need to be
if any error comes in the hardware the
user need to give attention to that
particular hardware it need to be
changed or it need to be taken care of
so that is one thing so here the
hardware interrupt may not be solvable
so so at that time the system will give
an information or information to the
user so that's what so that is a
hardware inter it comes to the software
interrupt the software interest can be
considered two different things two
different kinds one is a solvable and
non solvable so solve all means if any
error comes in the program execution so
that error can be solved by a system
routine so that maybe we call this a
solvable one but it another one is not
solvable at that time so like hardware
interact so the system will give an
intimation to the user so if the
solvable inter practice so what the
system will do system will stop the
current program execution or the current
operation will be stopped then it will
find the exact service notice or
interrupt service routine so which type
of interbeing occurred so for that the
interrupt service routine will be
identified so that service no team will
be taken it will be executed then that
particular interval be solved then the
Graham execution control will be given
to the older one then the regular
execution will be started so this is
called software interrupt and this is
how the software entered may be solved
then one more advantage is there so
nowadays if you're checking the
programmers are using the inter for the
multitasking so the the operating system
is in the unique processor system so
after time it can be handled only one
process of the time so if you want to
change that particular characteristics
so what you can do you can give an
interval so the programmer can use the
interrupt to switch the concludes from
one program to another program so it can
give a facility of multitasking so this
is all about interrupts so there are two
types of mentor one is a hardware
interest and second one is the software
interrupt so the software Incred may be
called as trap so the software in Turkey
solvable by entered service Odom so
interrupt service protein is a system
programs so list of system programs may
be may be bit the operating system so
operating system will select the
particular service floating according to
which but in trip has been occurred so
based on that the service loading will
be taken it will be supporting the
problem-solving off soft software
interrupt so this is all about
interrupts thank you
