Secondary Level Mask Bit:-
It disables service from an individual source or source group. |
|
Status Register:-
A read only register for a device to set a flag on arising of an interrupt. A user instruction can also reset a bit in it. If a device has number of sources the status register has number of flags, a distinct source for each source. when it is read by a processor instruction the flag resets. |
|
Stack Frame:-
A set of registers or a memory block that stores the context for a program or ISR(Interrupt Service Routine). |
|
Software Interrupt:-
An interrupt by an instruction, by a software timer or an error condition trap or illegal opcode. |
|
Signal:- An exception may also sometimes be called a signal. The processor may also signal an exception.
Example:- On division by zero in 80x86. |
|
Software Assigned Priority:-
A priority for a source or source group. It is defined at a register called interrupt priority register. When several interrupts occur at the same time, software assigned priorities override the hardware priorities. |
|
Strength Of materials:-
Strength of materials deals with the ability of various types of materials to resist its failure and their behavior under the action of the forces. |
|
Scalar:-
Scalar quantities are those which have only magnitude but no direction. Example:- mass, volume, density. |
