Glossary

A

address:

The location of program code or data stored; an individually

accessible memory location.

A-law companding:

See compress and expand (compand).

API:

See application programming interface.

application programming interface (API):

Used for proprietary

application programs to interact with communications software or to
conform to protocols from another vendor’s product.

assembler:

A software program that creates a machine language program

from a source file that contains assembly language instructions,
directives, and macros. The assembler substitutes absolute operation
codes for symbolic operation codes and absolute or relocatable
addresses for symbolic addresses.

assert:

To make a digital logic device pin active. If the pin is active low, then

a low voltage on the pin asserts it. If the pin is active high, then a high
voltage asserts it.

B

bit:

A binary digit, either a 0 or 1.

big endian:

An addressing protocol in which bytes are numbered from left

to right within a word. More significant bytes in a word have lower
numbered addresses. Endian ordering is specific to hardware and is
determined at reset. See also little endian.

block:

The three least significant bits of the program address. These

correspond to the address within a fetch packet of the first instruction
being addressed.
