International Organization for Standardization
An organization that sets standards in many businesses and technologies, including
computing and communications.
Interrupt
A signal to the CPU that suspends the execution of a running application and transfers
control to an Interrupt Service Routine (ISR) so that the event may be processed.
Interrupt Handler
A routine that processes special code when an interrupt occurs.
Interrupt Request
An event which causes the processor to temporarily suspend normal instruction execution
and to start executing an interrupt handler routine. Some processors have several
interrupt request events allowing different priority interrupts.
Interrupt Service Routine
A function that is invoked when an interrupt occurs.
IRQ
See Interrupt Request.
ISO
See International Organization for Standardization.
ISR
See Interrupt Service Routine.
L-value
An expression that refers to an object that can be examined and/or modified. An l-value
expression is used on the left-hand side of an assignment.
Latency
The time between an event and its response.
Librarian
See Archiver.
Library
See Archive.
Linker
A language tool that combines object files and libraries to create executable code,
resolving references from one module to another.
Linker Script Files
Linker script files are the command files of a linker. They define linker options and
describe available memory on the target platform.
Little Endianess
A data ordering scheme for multibyte data whereby the least significant byte is stored
at the lower addresses.
Machine Code
The representation of a computer program that is actually read and interpreted by the
processor. A program in binary machine code consists of a sequence of machine
instructions (possibly interspersed with data). The collection of all possible instructions
for a particular processor is known as its “instruction set”.
