Glossary

clock cycle:

A periodic or sequence of events based on the input from the

external clock.

clock modes:

Options used by the clock generator to change the internal

CPU clock frequency to a fraction or multiple of the frequency of the input
clock signal.

code:

A set of instructions written to perform a task; a computer program or

part of a program.

codec:

Coder-decoder, or compression/decompression. A device that

codes in one direction of transmission and decodes in another direction
of transmission.

coder-decoder or compression/decompression (codec):

A device that

codes in one direction of transmission and decodes in another direction
of transmission.

compiler:

A computer program that translates programs in a high-level lan-

guage into their assembly-language equivalents.

compress and expand (compand):

A quantization scheme for audio sig-

nals in which the input signal is compressed and then, after processing,
is reconstructed at the output by expansion. There are two distinct com-
panding schemes: A-law (used in Europe) and

-law (used in the United

States).

constant:

A fixed or invariable value or data item that can be used as an op-

erand.

control register:

A register that contains bit fields that define the way a de-

vice operates.

control register file:

A set of control registers.

CSL:

See chip support library.

CSL module:

The CSL module is the top-level CSL API module.It interfaces

to all other modules and its main purpose is to initialize the CSL library.

DAT:

Data; see DAT module.

DAT module:

The DAT is an API module that is used to move data around

by means of DMA/EDMA hardware. This module serves as a level of ab-
straction that works the same for devices that have the DMA or EDMA
peripheral.
